A New Testing Method for Ceramic Hip Joint Heads According Conditions In Vivo
A new test method for the determination of the static burst strength of ceramic hip joint heads is described. The common test method is the test with an axial direction of the compressive force. In the following publication a finite element analysis of the stress distribution in ceramic heads under angular loading is shown. The results concerning the location of the highest hoop and tensile stresses are compared with the results of experimental tests for the determination of the static burst load of ceramic heads under a load direction of 25°.
