摘要：

Radial fretting tests of human cortical bone against two kinds of diameters titanium (TA2) balls were conducted. The damages of cortical bone aggravated with increase in the normal loads and cycles. Cracks propagating on the surface of cortical bone can be classified into four patterns among which the cracks propagated along the cement line were the most popular types. Critical load for crack initiation was also deduced to help analyzing the cause of the implant failure.
