The core idea of our approach is the introduction of\n            <jats:italic>embedded space<\/jats:italic>\n            \u2014the least-squares best fit of the material's rest state into three dimensions. Nearest-neighbor queries in the embedded space efficiently update particle neighborhoods to account for plastic flow. These queries are simpler and more efficient than remeshing strategies employed in mesh-based finite element methods. We also introduce a new estimate for the volume of a particle, allowing particle masses to vary spatially and temporally with fixed density. Our approach can handle simultaneous extreme elastic and plastic deformations. We demonstrate our approach on a variety of examples that exhibit a wide range of material behaviors.\n          <\/jats:p>","DOI":"10.1145\/2560795","type":"journal-article","created":{"date-parts":[[2014,4,15]],"date-time":"2014-04-15T17:50:29Z","timestamp":1397584229000},"page":"1-9","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":31,"title":["Deformation embedding for point-based elastoplastic simulation"],"prefix":"10.1145","volume":"33","author":[{"given":"Ben","family":"Jones","sequence":"first","affiliation":[{"name":"University of Utah, Salt Lake City, UT"}]},{"given":"Stephen","family":"Ward","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, UT"}]},{"given":"Ashok","family":"Jallepalli","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, UT"}]},{"given":"Joseph","family":"Perenia","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, UT"}]},{"given":"Adam W.","family":"Bargteil","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, UT"}]}],"member":"320","published-online":{"date-parts":[[2014,4,8]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1276377.1276437"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2012.87"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1276377.1276397"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2019406.2019409"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9991(86)90211-1"},{"volume-title":"Proceedings of the ACM SIGGRAPH\/Eurographics Symposium on Computer Animation. 28--36","author":"Bridson R.","key":"e_1_2_2_6_1"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2451236.2451243"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/1073368.1073400"},{"key":"e_1_2_2_9_1","unstructured":"K.
