    • Effect of extrusion ratio on paraffinic mineral oil lubricant in cold forward extrusion 

      Mohd Hafis, Sulaiman; Mohd Ridzuan, Mohd Jamir; Imaduddin Helmi, Wan Nordin; Syahrullail, Samion, Dr. (American Institute of Physics, 2012)
      A finite element (FE) analysis is made for steady-state two-dimensional forward extrusion with three different extrusion ratio values. Predicting extrusion force of aluminum billet extruded with palm oil lubricant will ...
    • Effect of sintering time on the properties of LaYO3 doped with ZrO2 solid electrolyte 

      Salmie Suhana, Che Abdullah          ; Nur Hazwani, Samsudin; Najwa Shafiqa, Anwar; Imaduddin Helmi, Wan Nordin (Trans Tech Publications, 2013)
      LaYO3 doped-ZrO2ceramic with the composition La0.95Zr0.05YO3+δ was prepared via the solid state reaction. The samples were sintered at 1450 °C and sintering times in range of 6-15 hours have been varied for both doped and ...
    • Effects of case depth, side-face carburizing and helix angle on residual stress and bending fatigue strength of case-carburized helical gears 

      Miyachika, Kouitsu; Ando, Kazuaki; Xue, Wei-Dong; Imaduddin Helmi, Wan Nordin (ASME, 2009)
      This paper presents a study on effects of case depth, side-face carburizing and helix angle on the residual stress and the bending fatigue strength of case-carburized helical gears. The carbon content of each element of ...
    • Effects of rim and web thicknesses on root stresses of thin-rimmed helical gear 

      Imaduddin Helmi, Wan Nordin; Mohd Hafis, Sulaiman; Daing Idris, D. M N; Che Abdullah, S. S; Miyachika, Kouitsu; Ando, Kazuaki; Koide, Takao (Applied Mechanics and Materials, 2012)
      This paper presents a study on root stresses of thin-rimmed helical gears with web arrangement of various rim and web thickness. Thin-rimmed helical gears used in this study were meshed with solid helical gear. Root ...
    • Load-displacement behavior of RBD palm stearin oil lubricant quantity in cold extrusion 

      Mohd Hafis, Sulaiman; Mohd Ridzuan, Mohd Jamir; Mohd Afendi, Rojan; Imaduddin Helmi, Wan Nordin; Boon, Raymond Whee Heng; Syahrullail, Samion, Dr. (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      Large consumption of lubricant may affect the environment due to their high potential of pollution. Therefore, there is significant demand to provide a solution to this current condition by using alternative lubricant ...
    • Strength and fracture characteristics of shear adhesive dissimilar joint 

      Mohd Afendi; Imaduddin Helmi, Wan Nordin; Ruslizam, Daud; Teramoto, Tokuo (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      In this study, the effect of bond thickness upon the shear strength of epoxy adhesively bonded joint with dissimilar adherends is addressed. The bond thickness, t between the adherends is controlled to be ranged from ...
