Abstract:
This paper introduces a simple method for simulating highly anisotropic elastoplastic material behaviors like the dissolution of
fibrous phenomena (splintering wood, shredding bales of hay) and materials composed of large numbers of irregularly-shaped
bodies (piles of twigs, pencils, or cards). We introduce a simple transformation of the anisotropic problem into an equivalent
isotropic one, and we solve this new “fictitious” isotropic problem using an existing simulator based on the material point
method. Our approach results in minimal changes to existing simulators, and it allows us to re-use popular isotropic plasticity
models like the Drucker-Prager yield criterion instead of inventing new anisotropic plasticity models for every phenomenon we
wish to simulate.
