The Effect of Bottom Profile Dimples on the Femoral Head on Wear in Metal-on-Metal Total Hip Arthroplasty.
Jamari Jamari,Muhammad Imam Ammarullah,Amir Putra Md Saad,Ardiyansyah Syahrom,Mohammad Uddin,Emile van der Heide,Hasan Basri +6 more
TL;DR: In this article, the effect of surface texturing as dimples on the wear evolution of total hip arthroplasty was investigated by developing finite element analysis from the prediction model without dimples and with bottom profile dimples of flat, drill, and ball types.
Journal ArticleDOI
Computational Contact Pressure Prediction of CoCrMo, SS 316L and Ti6Al4V Femoral Head against UHMWPE Acetabular Cup under Gait Cycle
Jamari Jamari,Muhammad Imam Ammarullah,Gatot Budi Santoso,Sony Sugiharto,Toto Supriyono,Akbar Teguh Prakoso,Hassan Basri,E. van der Heide +7 more
TL;DR: The results show Ti6Al4V-on-UHMWPE is able to reduce cumulative contact pressure compared to SS 316L- on-UhMWPE and CoCrMo-on theUH MWPE at peak loading.
Journal ArticleDOI
An elastic–plastic contact model of ellipsoid bodies
Jamari Jamari,Dirk J. Schipper +1 more
TL;DR: A theoretical model for the elastic-plastic contact of ellipsoid bodies is presented in this paper, which is verified by experimental results and is compared with published theoretical models, and very good agreement between the present model and the experimental results are found compared to the prediction of the other contact models.
Journal ArticleDOI
Minimizing Risk of Failure from Ceramic-on-Ceramic Total Hip Prosthesis by Selecting Ceramic Materials Based on Tresca Stress
Muhammad Imam Ammarullah,Gatot Budi Santoso,Sony Sugiharto,Toto Supriyono,Dwi Basuki Wibowo,Ojo Kurdi,Mohammad Tauviqirrahman,Jamari Jamari +7 more
TL;DR: In this article , a two-dimensional axisymmetric finite element-based computational model has been used to evaluate the Tresca stress on ceramic-on-ceramic coupling under gait cycle.
Journal ArticleDOI
In Silico Contact Pressure of Metal-on-Metal Total Hip Implant with Different Materials Subjected to Gait Loading
Jamari Jamari,Gatot Budi Santoso,Sony Sugiharto,Toto Supriyono,Muhammad Imam Ammarullah,E. van der Heide +5 more
TL;DR: In this paper , the authors investigated three different metallic materials, namely cobalt chromium molybdenum (CoCrMo), stainless steel 316L (SS 316L), and titanium alloy (Ti6Al4V) for application in metal-on-metal bearing of total hip implant in terms of contact pressure.
