Standard Test Method for Finite Element Analysis (FEA) of Non-Modular Metallic Orthopaedic Hip Femoral Stems

Importancia y uso:

3.1 This standard is applicable to the calculation of stresses seen on a femoral hip stem when loaded in a manner described in ISO 7206-4. This method can be used to establish the worst-case size for a particular implant. When stresses calculated using this method were compared to the stresses measured from physical strain gauging techniques performed at two laboratories using two different methods, the results correlated to within 8 %.

3.2 This test method can be used to estimate the effects of design variables on the stress and strain of metallic hip femoral stems in a setup mimicking that described in ISO 7206-4.
