Integral-Based Material Point Method and Peridynamics Model for Animating Elastoplastic Material.
Journal: LNCS:Transactions on Computational Science
This paper exploits the use of Material Point Method (MPM) for graphical animation of elastoplastic materials and fracture. Previous partial derivative based MPM studies face challenges of underlying instability issues of particle distribution and the complexity of modeling discontinuities. This paper incorporates the state-based peridynamics structure with the MPM to alleviate these problems, which outweighs diferential-based methods in both accuracy and stability. The deviatoric flow theory and a simple yield function are incorporated to animate plasticity.
