    • Coefficient of restitution of sports balls: A normal drop test 

      Adli, Haron; Khairul Azwan, Ismail, Dr. (IOP Publishing Ltd., 2012-12-05)
      Dynamic behaviour of bodies during impact is investigated through impact experiment, the simplest being a normal drop test. Normally, a drop test impact experiment involves measurement of kinematic data; this includes ...

    • 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 ...

    • 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 ...

    • Effect of NaVO3 concentration on corrosion resistance of conversion coating on AZ91D magnesium alloy 

      N.F.W.M., Sidik; Mohd Zamzuri, Mohammad Zain; Mokhtar, Mat Salleh; Khairul Azwan, Ismail, Dr. (Trans Tech Publications, 2012)
      Anticorrosive oxide films were successfully prepared on AZ91D magnesium alloy by chemical conversion coating in La (NO3)3 electrolytes with and without NaVO3. The morphologies and chemical composition were characterized ...

    • 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, Dr.; Nooraizedfiza, Zainon (Trans Tech Publications, 2012)
      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 ...

    • 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, ...

    • Strength of the weld line and warpage defects on the molded parts in injection molding process 

      S. M., Nasir; Khairul Azwan, Ismail, Dr.; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib (Praise Worthy Prize S.r.l., 2013)
      Strength at weld the line location and warpage problem in injection molding plastic component were not new problems in injection molding industries. Many researchers had emerged with several improvement techniques to reduce ...
