Micropolar Elasticity in Physically-Based Animation
(ACM Association for Computing Machinery, 2023)
We explore micropolar materials for the simulation of volumetric deformable solids. In graphics, micropolar models have only been used in the form of one-dimensional Cosserat rods, where a rotating frame is attached to ...
A Generalized Constitutive Model for Versatile MPM Simulation and Inverse Learning with Differentiable Physics
(ACM Association for Computing Machinery, 2023)
We present a generalized constitutive model for versatile physics simulation of inviscid fluids, Newtonian viscosity, hyperelasticity, viscoplasticity, elastoplasticity, and other physical effects that arise due to a mixture ...
