SUMMARY:Q3T Prisms: A Linear-Quadratic Solid Shell Element for Elastoplast
 ic Surfaces
DESCRIPTION:Technical Papers\n\nJuan Sebastian Montes Maestre, Stelian Cor
 os, and Bernhard Thomaszewski (ETH Zürich)\n\nWe introduce a novel approac
 h for simulating elastoplastic surfaces using quadratic through-the-thickn
 ess (Q3T) solid shell elements. 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
