Nasir, Mat Saad; Khairul Azwan, Ismail; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib (Trans Tech Publications, 2013-12)In this study, a mold is designed in single and dual type of gate in order to investigate the deflection of warpage for thick component in injection molding process. Autodesk Moldflow Insight software was used as a medium ... -
Dynamic axial crushing of empty and foam-filled conical aluminium tubes: Experimental and numerical analysis
Fauziah, Mat; Khairul Azwan, Ismail; Masniezam, Ahmad; Sazali, Yaacob; Inayatullah, Othman (Trans Tech Publications, 2014-09)This paper presents the crushing behaviour of empty and foam-filled conical tubes under axial dynamic loading. A nonlinear finite element (FE) model was developed and validated against experiments. The validated model was ... -
Effect of filler on the impact characteristics of aluminium tubes
Fauziah, Mat; Khairul Azwan, Ismail; Sazali, Yaacob; Masniezam, Ahmad (Taylor & Francis, 2014-12-18)This paper presents the behaviour of empty and foam-filled aluminium alloy (AA6061-T6) tubes under dynamic axial loading. The influence of geometrical and various densities of fillers was investigated by employing a finite ... -
The effect of room temperature on the generator’s winding coils temperature
Nor Zaiazmin, Yahaya; Khairul Azwan, Ismail; Muhamad Saifuldin, Abdul Manan; Atikah, Haji Awang (Trans Tech Publications, 2014)Thermal modeling is a method used to formulate a temperature profile for a generator. The most common types of thermal model used by researchers are transient and steady-state model. There is insufficient of information ... -
An experimental and numerical analysis of empty and foam-filled aluminium conical tubes under oblique impact loading
Fauziah, Mat; Khairul Azwan, Ismail; Sazali, Yaacob (Trans Tech Publications, 2013)This paper presents the crushing behaviour of empty and foam-filled conical aluminium alloy (AA6061-T6) tubes under oblique impact loading using a validated nonlinear finite element (FE) code, LS-DYNA. The study aims to ... -
Experimental and numerical analysis of foam-filled aluminum conical tubes subjected to oblique impact loading
Fauziah, Mat; Khairul Azwan, Ismail; Sazali, Yaacob; Zaini, Ahmad (Carl Hanser Verlag GmbH & Co. KG., 2014)This study aims to investigate the response of AA6061-T6 conical tubes under oblique impact loading, for variations in filler density and tube material by using experimentally validated model. Good correlations between the ... -
Experimental modal analysis of a golf clubface: Investigation of trampoline effect
Khairul Azwan, Ismail; Stronge, W. J. (Vibromechanika, 2010-12)A complete modal analysis of a golf clubface has been presented in order to investigate the 'trampoline effect'. The availability of titanium golf drivers with thin, flexible faces opens up the opportunity to design the ... -
Impact models and coefficient of restitution: A review
Ahmad, M. ,; Khairul Azwan, Ismail; Mat, F. (Asian Research Publishing Network, 2016-05-20)Impact is a complicated phenomenon that occurs when two or more bodies collide at a short time period. Impact model is used to determine the responses of the contact bodies due to the impact event. Furthermore, energy loss ... -

Mohd Zamzuri, Mohammad Zain; Suhaimi, Illias; Mokhtar, Mat Salleh; Khairul Azwan, Ismail; Nooraizedfiza, Zainon (Scientific.net, 2012-06-26)Anodization is a useful technique for forming protective films on magnesium alloys and improves its corrosion resistance. Based on the rare earth metal (REE) salt solution, the optimum parameter was selected by comparing ... -
Modeling and numerical simulation for the newly designed four cavity blades vertical axis wind turbine
Suffer, Kadhim; Usubamatov, Ryspek; Abdul Quadir, Ghulam; Khairul Azwan, Ismail (Trans Tech Publications, 2014)The last years have proved that Vertical Axis Wind Turbines (VAWTs) are more suitable for urban areas than Horizontal Axis Wind Turbines (HAWTs). To date, very little has been published in this area to assess good performance ... -
A new approach to reduce the thermal modeling experiment time by estimating the settling time
Nor Zaiazmin, Yahaya; Khairul Azwan, Ismail; Mohd Saifuldin, Abdul Manan; Atikah, Haji Awang (Trans Tech Publications, 2014)In order to develop a thermal model for a generator or a motor, several experiments need to be conducted. One of the challenges in conducting the experiment is that it consumes a lot of time to reach its steady state ... -
