摘要：
The author implemented the numerical analysis algorithm based on the particle based analysis method, GIMPM (Generalized Interpolation Material Point Method) and applied it to simulations of triaxial compression tests. Although GIMPM is a derivative of MPM, it has more stable numerical algorithm and removes numerical noises, which are generated when material points cross numerical grids. In this paper, to simulate triaxial compression tests, numerical damping and material non-linearity (Mohr-Coulomb constitutive model) are implemented. The results obtained by simulations are compared with experimental results. And the effectiveness of GIMPM is confirmed.
