YY/T 1714-2020 Standard methods for finite element analysis (FEA) of non-modular metallic orthopaedic hip femoral stems
Basic Information
Scope
This standard specifies the requirements and considerations for numerical simulation methods used in the stress and strain analysis of non-modular metal hip joint femoral stems (i.e., integrated femoral stems that are only connected to the femoral head by a conical connection) using finite element analysis (FEA) technology. This standard is only applicable to cases where the stress is lower than the yield strength (which can be obtained from the material specification).
This standard specifies the requirements and considerations for the development of finite element models aimed at predicting the static stress and strain of implants in the evaluation of non-modular metal hip joint femoral stems. This standard is applicable to the evaluation of the worst-case scenarios of a series of implant specifications, with the aim of improving the efficiency of physical testing. This standard recommends procedures for model inspection and verification, which help determine whether FEA complies with the requirements of this standard. This standard recommends the content that should be included in the mechanical simulation engineering report.
This standard is only applicable to the static structural analysis of non-modular metal hip joint femoral stems, and does not include the prediction of fatigue strength.
Note: This standard uses the International System of Units.
