Constitutive Law
This MPM Material is an isotropic, elastic-plastic material in large strains using a hyperelastic formulation. The elastic part is a neo-Hookean material. Plasticity occurs when the elongation in either tension of compression reaches a critical value. This material is based on similar material using in a paper to animate snow mechanics.
Material Properties
The material properties are given in the following table.
