2020 , Khor Chu Yee , Mohd Al-Hafiz Mohd Nawi , Muhammad Ikman Ishak , Z. X. Wei , Mohd Uzair Mohd Rosli

Cyclone gasifier is used as the energy conversion system for the biomass. The design and material selection for the cyclone gasifier is important, which affect the strength of the gasifier during the operation. This research aims to investigate the effect of the various materials to the mechanical aspects (i.e., stress, strain and displacement) of the cyclone gasifier. The mechanical aspects analysis is carried out by using the finite element (FE) based software. The stress, strain and displacement of the cyclone gasifier’s structure was analyzed for various stainless steel materials (i.e., ferritic (FSS), AISI 316, 1023 CSS, 201 ASS and AISI 4130). The finite element analysis revealed the use of 201 ASS experienced highest stress (221 MPa). Lowest strain and displacement were found on 201 ASS and 1023 CSS, respectively. These research findings are expected to be used as the reference for the engineer in the material selection process for the design and fabrication of cyclone gasifier.

Mechanical design and analysis of medical gloves remover

2023-12 , Muhammad Ikman Ishak , Mike Darren Jamba Anak Sikam , Wan Nur A'tiqah Wan Draman

Medical gloves play a pivotal role in ensuring clinical and hospital safety, as well as optimizing performance. Throughout the medical field, it has been traditionally understood that medical gloves function as a vital barrier, safeguarding both healthcare providers and patients, thereby diminishing the transmission of infections. Presently, healthcare personnel take off their medical gloves manually, using their hands, before discarding them. Should healthcare workers not diligently follow post-precautionary practices, including thorough handwashing and sanitization, the potential for infection increases significantly. Consequently, it is imperative for this study to explore methodologies for the proper removal of used medical gloves from hands, eliminating the need for direct contact prior to disposal. The primary goal of this study was to design and analyse a removal tool for used medical gloves tailored to minimize the risk of infection. Primary and secondary data were procured through the utilization of observation, interviews, and scholarly journal articles. This was succeeded by a progressive sequence involving the evolution of design concepts, the creation of three-dimensional models, rigorous analytical procedures, and comprehensive assessments of usability. The results of our investigation indicate that the suggested configuration of the medical gloves remover is deemed acceptable with regard to its incorporated features, including the adaptable gloves remover structure, main housing, front panel, disposal bin, and bracket for attachment. However, potential refinements may be requisite to amplify the design’s overall efficacy in facilitating the touchless removal of used medical gloves.

Influence of material properties on the fluid-structure interaction aspects during molded underfill process

2017 , C.Y. Khor , Muhammad Ikman Ishak , M.U. Rosli , Mohd Riduan Jamalludin , M.S Zakaria , A.F.M. Yamin , M.S. Abdul Aziz , M.Z. Abdullah

This paper presents the investigation of the effects of epoxy moulding compound’ (EMC) viscosity on the FSI aspects during moulded underfill process (MUF). Finite volume (FV) code and finite element (FE) code were connected online through the Mesh-based Parallel Code Coupling Interface (MpCCI) method for fluid and structural analysis. The EMC flow behaviour was modelled by Castro-Macosko model, which was written in C language and incorporated into the FV analysis. Real-time predictions on the flow front, chip deformation and stress concentration were solved by FV- and FE-solver. Increase in EMC viscosity raises the deformation and stress imposed on IC and solder bump, which may induce unintended features on the IC structure. The current simulation is expected to provide the better understandings and clear visualization of FSI in the moulded underfill process.

Experimental and computational evaluations of the mechanical stresses of banana trunk fibre-reinforced epoxy resin composite in coffee table application

2020 , Muhammad Ikman Ishak , Mohd Uzair Mohd Rosli , Khor Chu Yee , C N Ismail , Mohd Al-Hafiz Mohd Nawi

The banana plant including the trunk is normally disposed after it has produced fruits once in its lifetime and becoming unproductive. Herbicide injection and burning using kerosene are the examples of current disposing method. Those methods are unfavourable owing to bad effects to the environment. Therefore, the unproductive banana trunk through its fibre properties, has a high potential to be used as composite in saving the environment. Three tensile test specimens were prepared with two of them have different length of banana fibres – shorter and longer than 0.5 mm, whilst another specimen has no fibres. The elastic modulus, Poisson’s ratio, and vertical load of 2 GPa, 0.3, and 981 N, respectively, were applied towards numerical models. The results exhibited that the composite with short banana fibre length promoted encouraging maximum and break stress values. Besides, the properties of the composite are well appropriate to be applied in furniture making as satisfactory stress value recorded in the computational analysis.

Mechanical Design and Analysis of New Staircase Climbing Hand Truck

2023-06-15 , Muhammad Ikman Ishak , Dir Fazly Pailin

The transportation of goods on a staircase could give challenges to the users, especially those stay in a high-rise building particularly when the elevators are not in service. There is a variation of existing staircase climbing hand truck designs has been developed; however, some problems were identified. The existing designs have a limitation in terms of wheel system configuration to be used on different staircase sizes. Besides, the designs also possess limited supporting structure areas to accommodate the goods and are less ergonomic for handling and downsizing. The objective of the study was to design a new staircase climbing hand truck that was completed with new functional and ergonomic features to improve the climbing process. Primary and secondary data were collected via observation, interview, and journal articles, followed by design concept development, three-dimensional modelling and analysis, and usability testing. Our findings showed that the proposed design of the hand truck is satisfactory in terms of developed features such as an adjustable wheel frame, foldable nose plate, safety compartments and cables, and adjustable handle. Further improvements might be necessary to enhance the design functionality of the hand truck for the transportation of goods on a staircase.

The aim of this present work was to investigate the effect of different percentage rice husk silica (RHS) particles composition towards polymer mixed matrix membrane microstructure and performance in water separation process. The polymer membranes were prepared by a phase inversion method using polysulfone (PSf), N-methyl-2-pyrrolidone (NMP) as solvent, distilled water as non-solvent and fixed RHS at 400°C as an additive. The microstructures of PSf/PEG/RHS sample were characterized by performing scanning electron microscope (SEM). The performance was measured by using pure water flux and humic acid for the rejection test. The analyzed result of SEM analysis revealed that the addition of RHS obviously improved the microstructure of the membrane especially at the top and sub layer at the range of 1 until 3 wt. %. This was proven by the pure water flux (PWF) value measured from 114.47 LMH to 154.04 LMH and rejection from value 83% to 96% at this specified range substantially higher than the mixed matrix membrane with synthetic silica. In fact, the presence of RHS particles not only improved the properties and performance of membrane but also possess biodegradable properties which can minimize the pollution and provide a membrane green technology system.

Todays, there are various of optimisation methods that have been studied by many researchers in order to find the appropriate combination of processing parameters setting in the injection moulding process. From the previous literatures, the optimisation works have been proven will improve the moulded part quality. In this study, the application of optimisation work to improve warpage of front panel housing has been explored. By selecting cooling time, coolant temperature, packing pressure and melt temperature as the variable parameters, design of experiment (DOE) have been constructed by using the rotatable central composite design (CCD) approach. Response Surface Methodology (RSM) was performed in order to define the optimal processing parameters setting which will optimise the warpage condition. Based on the results, melt temperature is the most significant factor contribute to the warpage condition and warpage have optimised by 47.1% after optimisation. The findings show that the application of optimisation work offers the best quality of moulded part produced.

2020-11-02 , Khor Chu Yee , Siti Nor Azreen Ahmad Termizi , Muhammad Ikman Ishak , Hissam M.I.B. , Ani F.C.

The thermal environment may cause the unintended thermal stress to the solder joint which could lead to the reliability issue. This study aims to study the temperature cycling analysis of various solder materials (i.e., Sn-58Bi, Sn-3.5Ag and Sn-9Zn) by using the finite element method. A leadless solder joint of the surface mount component was considered and the three-dimensional model was created in the simulation software. The thermo-mechanical aspects (i.e., maximum displacement, stress and strain) of lead-free solder materials were investigated. The simulation results revealed the solder material significantly affects the thermo-mechanical aspects during the temperature cycling test. The maximum stress of the leadless solder joint was concentrated around the interface region of the solder and pad. The lowest stress (195MPa) was noticed on the solder joint when the Sn-58Bi material was applied. This study is expected to provide the understanding of the thermo-mechanical aspects of various solder materials during the temperature cycling test.

2020 , Khor Chu Yee , Mohd Al-Hafiz Mohd Nawi , Muhammad Ikman Ishak , Kee Wei Chin , Mohd Uzair Mohd Rosli , Mohd Riduan Jamalludin , Siti Nor Azreen Ahmad Termizi

The thermal management in the electronic device or system using the heat sink is important to ensure the device or system operating under the allowable temperature. The present study aims to investigate the thermal characteristic (i.e., temperature distribution) of the various heat sink designs via computational fluid dynamics (CFD) analysis. The electronic cooling process of the heat sink is carried out via CFD software. The temperature distribution of the various heat sink designs (i.e., plate fin, circular pin fin and rectangular fin) was analyzed and compared. The CFD analysis revealed the plate fin heat sink has lowest temperature distribution on the fin region. High temperature distribution was observed on the pin fin heat sink. The non-uniform temperature distribution was attributed by the direction of inlet airflow, whereas the low temperature was found in the region that close to the inlet airflow. Thus, the research findings indicated the design of heat sink significantly affects the temperature distribution during the electronic cooling process.
