AI Technical Summary
The existing bone tissue model is difficult to take into account the detailed anatomical structure of composite bone tissue and the implementation of finite element simulation, resulting in insufficient accuracy of simulation results.
The composite bone tissue modeling method with a pore gradient discrete embedded type is adopted. By establishing a three-phase composite bone tissue geometric model with discrete random pores, and a material constitutive model of cortical bone and cancellous bone is established, and finally meshing is performed to achieve finite element simulation.
It improves the accuracy of bone model simulation and can more accurately simulate the composite structure of bone tissue transition from cortical bone to cancellous bone, solving the problem of constitutive homogeneity distortion of existing bone tissue cutting simulation materials.
