Trends of mechanical consequences and modeling of a fibrous membrane around femoral hip prostheses [PDF]

, 1990
In the present study, the effects of a fibrous membrane between cement and bone in a femoral total hip replacement were investigated. The study involved the problem of modeling this fibrous membrane in finite-element analyses, and its global consequences

Calculation of wear (f.i. wear modulus) in the plastic cup of a hip joint prosthesis [PDF]

, 1975
The wear equation is applied to the wear process in a hip joint prosthesis and a wear modulus is defined. The sliding distance, wear modulus, wear volume, wear area, contact angle and the maximum normal stress were calculated and the theoretical ...

Patient-individual hip cups: simulation-based design and sheet metal forming manufacturing [PDF]

, 2013
The revision of an hip prosthesis can have different reasons. One frequent cause, especialley after implantation of a conventional cup, is the so called stress-shielding effect which can lead to a migration or loosening.
