    • Bending fatigue strength of case-carburized spur gears with boss 

      Imaduddin Helmi, Wan Nordin; Mohd Afendi, Rojan; Salmie Suhana, Che Abdullah; Mohd Hafis, Sulaiman (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      Studies on the spur gear, to increase the bending fatigue strength have been published by adopting gear with high pressure angle and positive addendum modification factor. However, studies on the spur gear with wide ...

    • 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 ...

    • 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 ...
