Computerized rendering of objects having anisotropic elastoplasticity for codimensional frictional contact

摘要

At least some embodiments of the present disclosure relate to a method of visualizing objects having frictional contact. The method includes transferring masses and momentums of a plurality of particles of an object to a grid including a plurality of grid nodes; updating momentums of the grid nodes based on the transferred masses and momentums of the particles; transferring the updated momentums of the grid nodes to the particles of the object; updating positions of the particles and deformation gradients of the particles based on the updated momentums of the grid nodes; projecting the deformation gradients for plasticity of the object; updating elastic components and plastic components of the object; and outputting a visualization of the object based on the positions of the particles of the object.
