Finite-Element Analysis and Optimization for Gradient Porous Structure of Artificial Bone

摘要：

　　The loading force of the artificial bone implanted into the human body and the flowing,growth and deposition of cells were influenced by the gradient porous structure.The software of ANSYS Workbench was used in the paper for the stress and strain analysis of the gradient porous structure of the established 3D artificial bone.The variation of the maximum equivalent stress and maximum equivalent strain and elastic modulus changed through the changing of the loading force and porosity.Basis on meeting the mechanical properties,the porosity was used as the index for the optimization of the porous structure of the artificial bone.And it also laid the foundation for the subsequent laser sintering.
