Modeling the mechanics of deformable surfa ces has been a cornerstone of graphics research for decades. Although thin shell models are suitable for many materials and applications, simulation -based planning of plastic forming processes requires attention to deforma tion in the thickness direction. Building on recent advances in the graphi cs community, we explore solid shell elements for modeling elastoplastic s urfaces. While linear prism elements perform well for compressible materia ls such as thick cloth and foam mats, they suffer from severe locking arti facts when applied to incompressible and plastic materials. Our analysis i dentifies the root cause of this issue as the inability to capture non-con stant strain in the thickness direction. Our new Q3T elements address this limitation with a minimal yet effective modification to linear prisms, re sulting in significantly improved performance with only a moderate increas e in computational cost. Through various examples, we demonstrate that our Q3T elements closely match the qualitative behavior of reference simulati ons and provide accurate quantitative results compared to real-world deep drawing experiments.\n\nRegistration Category: Full Access, Full Access Su pporter\n\nLanguage Format: English Language\n\nSession Chair: Huamin Wang (Style3D Research) URL:https://asia.siggraph.org/2024/program/?id=papers_1210&sess=sess123 END:VEVENT END:VCALENDAR
