  text: We present an extension to Lagrangian finite element methods to allow for
    large plastic deformations of solid materials. These behaviors are seen in such
    everyday materials as shampoo, dough, and clay as well as in fantastic gooey and
    blobby creatures in special effects scenes. To account for plastic deformation,
    we explicitly update the linear basis functions defined over the finite elements
    during each simulation step. When these updates cause the basis functions to become
    ill-conditioned, we remesh the simulation domain to produce a new high-quality
    finite-element mesh, taking care to preserve the original boundary. We also introduce
    an enhanced plasticity model that preserves volume and includes creep and work
    hardening/softening. We demonstrate our approach with simulations of synthetic
    objects that squish, dent, and flow. To validate our methods, we compare simulation
    results to videos of real materials.
