| Abstract: | The modeling method of functionally graded material human bones is proposed by the secondary development on the interface in Abaqus. The algorithm that uses user defined field subroutine(USDFLD) to solve large deformation and large displacement and the data transfer method are proposed, which avoids the complex user defined material subroutine(UMAT). The effect of mesh density on the analysis results and mesh convergence is researched to ensure the the rationality using finite element to discretize functionally graded material human bones. |
