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.","lang":"eng"}],"oa":1,"oa_version":"Submitted Version","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","date_created":"2020-11-17T09:35:10Z","publisher":"Wiley","scopus_import":"1","title":"A practical method for animating anisotropic elastoplastic materials","quality_controlled":"1","status":"public","doi":"10.1111/cgf.13914","page":"89-99","author":[{"first_name":"Camille","last_name":"Schreck","full_name":"Schreck, Camille","id":"2B14B676-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Wojtan, Christopher J","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","first_name":"Christopher J","last_name":"Wojtan","orcid":"0000-0001-6646-5546"}],"has_accepted_license":"1","publication":"Computer Graphics Forum","external_id":{"isi":["000548709600008"]},"publication_identifier":{"issn":["0167-7055"],"eissn":["1467-8659"]},"ec_funded":1,"article_type":"original","citation":{"chicago":"Schreck, Camille, and Chris Wojtan. “A Practical Method for Animating Anisotropic Elastoplastic Materials.” <i>Computer Graphics Forum</i>.
