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 ... -
Convergence of finite element model for crushing of a conical thin-walled tube
Masniezam, Ahmad; Khairul Azwan, Ismail, Dr.; Fauziah, Mat (Elsevier B.V., 2013)In this paper, a convergence of finite element model using different types and sizes of mesh modes has been conducted. A thin-walled conical tube was modeled using plane shell element in LS-DYNA software under dynamic axial ... -
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 heat treatment on microstructure and corrosion behavior of Az91d magnesium alloy
Chye, Lih T.; Mohd. Zamzuri, Mohammad Zain; Siti Norbahiyah, Mohamad Badari; Khairul Azwan, Ismail, Dr.; Mohd Nazree, Derman, Dr.; Suhaimi, Illias (Trans Tech Publications, 2013)An AZ91D ingot in the as-cast condition was homogenized by heat treatment process. Then, the microstructures produced and corrosion behaviour after heat treatment was studied in detail. As-cast AZ91D was recrystallize by ... -
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 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 ... -
Improvement of Corrosion Resistance of Rare Earth Element (REE)-Based Anodic Oxidation Coating on AZ91D Magnesium Alloy
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.

Mathematical models for productivity and availability of automated lines
Usubamatov, Ryspek, Prof. Dr.; Khairul Azwan, Ismail, Dr.; Jamali, Md Sah (Springer-Verlag London Limited., 2013-04)The basic attributes of any industrial machine are productivity rate, quality of products, as well as the cost and flexibility of manufacturing systems. Attributes of productivity are related to the theory of reliability, ... -
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.
