摘要: The mechanical properties of well-ordered porous materials are related to their geometrical parameters at the mesoscale. Finite element (FE) analysis is a powerful tool design by analysing behaviour. However, FE models often computationally expensive. This article aims develop cost-effective model simulate metallic for orthopaedic applications. Solid and beam modelling approaches compared, using finite size infinite media considering cubic unit cell geometry. then applied compare two geometries: diamond. Models having provide similar results than approach large sample sizes. In addition, these also capture influence boundary conditions on response small showed little computational cost solid approach. Diamond geometry appeared be more suitable applications
