Abstract
Mechanical properties of the various regions of cancellous bone and cartilage-cancellous bone composite of the human acetabulum were investigated.
Their elastic moduli and strengtns were almost the same as those of the femoral head, while their phase lags were lower than those of the femoral head.
Their regional difference of the mechanical properties was not so much as in the femoral head. This fact was considered to depend on the difference of the loading condition between the acetabulum and the femoral head.
Dynamic behavior of the acetabulum was also studied by a compression test.
