Study of an Additional Layer of Cement Mantle Hip Joints for Reducing Cracks

Journal of Functional Biomaterials, 2019
Failure of the cement mantle in total hip arthroplasty is not a simple phenomenon. Cracking, which can be caused by crack initiation and repeated loading, can cause loosening of the acetabular liner component.

An Investigation into the Relationships Determining Ball Trajectory in Mills by Using the Physical Modelling [PDF]

مجله مدل سازی در مهندسی, 2019
Since software packages, which predict the charge motion of single ball in the mineral processing tumbling mills, use the Powell (1991) relationships, the accuracy of these relationships was investigated in this research.

The Effect of Layer Variation Between Liner and Cement Mantle on Reducing Cracks of PMMA Material Hip Joints

E3S Web of Conferences, 2018
Failure of cement mantle of bond loosening between liner and cement mantle is an important issue in total hip replacement. Two factors that commonly cause cement mantle failure are initial crack and stress.
