The artificial joint is consisted with the upper structure of tungsten alloy steel and the lower part of polyethelene are applied with load. When this joint is applied with load in this study, the load distribution at the joint and the stress distribution of support hole to install the joint are investigated by finite element analysis. These results can be utilized at obtaining the basic material to have the experiment for the real thing. The crack is initiated as the load is concentrated at the end of corner on the upper structure. This behavior is in accord with a case of tissue damage due to the breakage of artificial joint reported at medical science.
