PublicationFatigue life investigation of UIC 54 rail profile for high speed rail( 2017-10-29)
;Gurubaran Panerselvan ; ;Nur Fareisha M. A. ; ;Haftirman I.This study is to investigate the fatigue life of high speed rail in Malaysia. This paper describes about the experimental and simulation analysis investigation on fatigue life of rail profile UIC 54 using bulk specimen according to ASTM E 466-15 standard. The Fatigue life testing was performed in the fatigue testing machine (Instron 8800) 100 kN. Meanwhile, the fatigue life analysis was performed in ANSYS Workbench 14.5. Furthermore, the stress levels for experimental testing were applied as 16.7%, 25%, 35%, 50%, 58.3%, 66.77% and 75% with machine frequency of 20 Hz. Apart from that, the total fatigue life cycles for rail profile UIC 54 were acquired from both experimental and simulation. The fatigue life S-N curves were plotted and validated with the results of the simulation analysis with experimental results. -
PublicationFinite element modelling of thin intermetallic compound layer fractures( 2017)
;Ooi Eang Pang ; ; ;A thin intermetallic compound (IMC) of solder ball joint induces strong stress concentration between the pad and solder where a crack propagated near the IMC layer. The fracture mechanism of the IMC layer is complex due to the effect of IMC thickness, crack length, solder thickness and Young’s Modulus. At present, there is still an undefined exact geometrical model correlation for numerical simulations of IMC layer fracture. Thus, this paper aims to determine the accuracy of IMC layer models subjected to crack-to-width length ratio (a/W) in correlation with the ASTM E399-83 Srawley compact specimen model using finite element (FE) analysis. Several FE models with different geometrical configurations have been proposed under 10 MPa tensile loading. In this study, the two dimensional linear elastic displacement extrapolation method (DEM) is formulated to calculate the stress intensity factor (SIF) at the crack tip. The study showed that with an error of 0.58% to 0.59%, a width of 2.1 mm and a height of 1.47 mm can be recommended as the best geometrical model for IMC layer fracture modelling which provides a wider range for a/W from 0.45 to 0.85 instead of from 0.45 to 0.55. This result is significant as it presents a method for determining fracture parameters at thin IMC layers with a combination of singular elements with meshes at different densities which is tailored to the Srawley model. -
PublicationInfluence of pre-heating technique on the titanium alloy for machinability using mill insert( 2023-10-27)
;Vemanaboina H. ;Ananda K.E. ; ;Naidu B.V.V.Pugazhenthi R.Ti6Al4V is a composite material with low density (4.5 g/cm3), melting point (16680C), and modulus of elasticity (107 GPa). Ti6Al4V's ambient temperature tensile values can reach 1400 MPa, and its yield strength is noted. The Ti6Al4V alloys are also extremely malleable, making them simple to make and machine. The cutting capabilities of titanium compound will be improved by introducing and registering a novel technique presented in this work. Pre-heating the workpiece with an induction coil heating device before end milling on a vertical machining centre will be studied (VC450-Spinner). WC-Co/PCD inserts placed 25 mm across the mill (R390-025B25-11M/R390-170408E-NLH13A) were thoroughly studied with general preheating method on Ti6Al4V machinability metrics like span of tool, Ra & Fc, noise, anomalies, tool, and morphology. Similarly, bare WC-Co was widely used in warmed machining (straight around multiple times compared to room temperature machining), and estimates of tool life are basically greater than those for cutting with PCD in room temperature machining. Preheated milling reduces shaking and noise, which in turn reduces cutting power and increases the lifespan of the tool. Preheated milling also increased chip-device contact length, lowering tool wear. The device also improved tool life and surface roughness by optimising cutting settings and preheating temperature. Lastly, preheating improved bare WC-Co execution and PCD tool life predictions under room temperature milling. By reducing disturbance and noise and the resulting cutting power, preheated milling promotes longer tool life. Preheated milling increases chip-tool contact length, which reduces tool wear. -
PublicationThe influence of shock wave surface treatment on vibration behavior of Semi-Solid State Cast Aluminum—Al₂SiO₅ composite( 2022)
;Paul Sureshkumar Samuel Ratna Kumar ;Peter Madindwa Mashinini ;Mahaboob Adam Khan ;Marimuthu Uthayakumar ;Ainagul Rymkulovna Toleuova ;Dariusz Mierzwiński ;Kinga KorniejenkoThe semi-solid state casting procedure was used to manufacture as-cast AA5083, 1 and 2 wt.% of aluminosilicate reinforced composite material. After solidification, developed as-cast materials were subjected to shock wave treatment in the subsonic wind tunnel. Various techniques were used to evaluate the change in shock wave exposure, including mechanical and structural analysis, which is a field dedicated to the study of vibrations and other material properties. The research methods involved developed material grain structure and surface morphology, such as field emission scanning electron microscope, X-ray diffraction, and the energy dispersive method. This study shows that the microhardness value of the matrix material is increased before and after exposure to shock wave treatment compared to the developed composite material. The natural frequency of the developed composite increases as a result of the addition of aluminosilicate reinforcement before and after the shock wave. In addition, the shifting of frequency mechanism is studied to know the influence of shock wave surface treatment. The results obtained show the potential of the application of this material in the area of robotic parts. -
PublicationExperimental Investigation on Bio-Machining of Nickel, Titanium and Nitinol (Shape Memory Alloys) Using Acidithiobacillus ferrooxidans Microorganisms( 2023-06-01)
;Pradeep M. ;Rajesh S. ;Uthayakumar M. ;Mathalai Sundaram C. ;Korniejenko K. ;Miernik K.Micromachining plays a vital role in the manufacturing industry in producing microcomponents with high sensitivity and fine dimensional tolerances for implant materials in medical applications. Micro-machining can be carried out through various machining processes like physical, chemical and biological processes, although the use of biological machining is limited. In biological machining, microorganisms are used as a source of energy to machine the components, and machining with microorganism brings a lot of advantages in the machining process like the production of components with lower energy resources, low cost, no heat-affected zone and fine dimensional tolerances, which makes it suitable for machining implant materials. In other machining process like conventional and unconventional machining processes, the heat-affected zone, dimensional tolerances and environmental-related problems are the major issues, as these processes generate more heat while machining. This damages the material, which will not be able to be used for certain applications, and this issue can be overcome by bio-machining. In this present work, nickel, titanium and nitinol are manufactured using the powder metallurgy technique. They are manufactured as a 10 mm diameter and 5 mm thick pellet. The fabricated nickel, titanium and nitinol shape memory alloys are machined with Acidithiobacillus ferrooxidans microorganisms to obtain a better material removal rate and surface roughness and to check the bio-machining performance by considering various parameters such as shaking speed, temperature, pH and percentage of ferric content for the future scope of biomedical applications. Considering these parameters, microorganisms play a vital role in the temperature, shaking speed and time of the bio-machining process, and it was observed that a better material removal rate and surface roughness are achieved at a temperature of 30 °C, shaking speed of 140 rpm and machining time of 72 h. -

PublicationExperimental investigation of thrust force, delamination and surface roughness in drilling hybrid structural composites( 2021-08-02)
;Shanmugam V. ;Marimuthu U. ;Rajendran S. ;Veerasimman A. ;Basha A.M. ; ;Neisiany R.E. ;Försth M. ;Sas G. ;Razavi S.M.J.Das O.Filled hybrid composites are widely used in various structural applications where machining is critical. Hence, it is essential to understand the performance of the fibre composites’ machining behaviour. As such, a new hybrid structural composite was fabricated with redmud as filler and sisal fibre as reinforcement in polyester matrix. The composite was then tested for its drilling performance. A comprehensive drilling experiment was conducted using Taguchi L27 orthogonal array. The effect of the drill tool point angle, the cutting speed, the feed rate on thrust force, delam-ination, and burr formation were analysed for producing quality holes. The significance of each parameter was analysed, and the experimental outcomes revealed some important findings in the context of the drilling behaviour of sisal fibre/polyester composites with redmud as a filler. Spindle speed contributed 39% in affecting the thrust force, while the feed rate had the maximum influence of ca. 38% in affecting delamination. -
PublicationTensile characterizations of oil palm empty fruit bunch (Opefb) fibres reinforced composites in various epoxy/fibre fractions( 2022-10-15)
; ; ; ;Tamrin S.B.M. ;Israr H.A. ; ;Guan N.Y. ; ;Kamis N.A.Oil palm empty fruit bunch (OPEFB) single fibers and reinforced composites were comprehensively characterized through tensile tests to assess their performance as potential reinforcing materials in polymer composites. The performances of OPEFB single fibers and reinforced composites with untreated and treated fibers conditions were compared. The fibers were variously treated with 3% sodium hydroxide, 2% silane, 3% sodium hydroxide mixed with 2% silane, and 3% sodium hydroxide prior to 2% silane for 2 hours soaking time. The highest toughness of the single fibers test was then selected to proceed with composites fabrication. The OPEFB composites were fabricated in 90:10, 80:20, 70:30, and 60:40 epoxy-fibre fractions. The result shows that the selected treated fiber composite exhibits better performance. The selected treated fiber composite increased the highest ultimate tensile strength by 145.3% for the 90:10 fraction. The highest Young’s Modulus was increased by about 166.7% for 70:30 fraction. Next, the highest toughness was increased by 389.5% for the 30:70 fraction. The treated fibers provided a better interlocking mechanism between the matrix and fibers in reinforced composites, thus improving their interfacial bonding. -
PublicationSurface characterization of laser-induced molten area in micro-grooving of silicon by ultraviolet (UV) laser( 2021-10-25)
;Raman N.S.A. ;Nordin I.H.W. ; ;Abdullah S.S.C.The objective of this research is to understand the fundamental mechanisms that govern the formation of laser-induced molten area during the micro-grooved fabrication on silicon material. In this research work, micro grooves were fabricated on silicon wafer by using ultraviolet (UV) laser of 248nm wavelength. Influence of lasing parameters such as pulse duration, laser pulse energy and scanning speed on the surface of micro-grooved was characterized. It is found that, the width of the micro grooves become wider with increasing laser pulse energy when ultraviolet laser was irradiated on silicon material. On the other hand, heat affected zone (HAZ) can be found at the surface of micro groove line at high pulse energy, high pulse repetition rate and lower scanning speed irradiation condition. This is considered due to the excessive heat input of the laser irradiation condition. It is concluded that proper selection of laser processing parameters of pulse energy, E, pulse repetition rate, Rp, and scanning speed is necessary to achieve high quality micro-grooves. -
PublicationDetermination of effective elastic properties of metal matrix composites with damage particulates using homogenization method( 2017-10-29)
;Halim S.Z. ; ; ;The present study aims to investigate the effect of micro-damage in particulates metal matrix composite on the elastic properties. The micro damage that perhaps could occurs during manufacturing process or due to environmental effects was modelled in three different types, namely shattered, debonded and breakage particulates with variation of volume fraction. The modelling and analysis were conducted based on homogenization theory by utilizing multiscale finite element software (Voxelxon). The results suggest that the elastic properties of metal matrix composite was sensitive to the geometrical defects of its particle.
