Cyclic Load Test

The specimen used in the previous test was still firmly fixed on the universal testing machine. For the cyclic loading test, a cyclic vertical load was applied to the specimen at a speed of 0.6 mm/s, with a cyclic force of 100–1000 N and frequency of 0.2 Hz. There were 50 cycles in each group. The load was removed, and the displacement of the femoral head was recorded after completing the cyclic loading test.
