SUMMARY:Q3T Prisms: A Linear-Quadratic Solid Shell Element for Elastoplast
 ic Surfaces
DESCRIPTION:Juan Sebastian Montes Maestre, Stelian Coros, and Bernhard Tho
 maszewski (ETH Zürich)\n\nWe introduce a novel approach for simulating ela
 stoplastic surfaces using quadratic through-the-thickness (Q3T) solid shel
 l elements. Modeling the mechanics of deformable surfaces has been a corne
 rstone of graphics research for decades. Although thin shell models are su
 itable for many materials and applications, simulation-based planning of p
 lastic forming processes requires attention to deformation in the thicknes
 s direction. Building on recent advances in the graphics community, we exp
 lore solid shell elements for modeling elastoplastic surfaces. While linea
 r prism elements perform well for compressible materials such as thick clo
 th and foam mats, they suffer from severe locking artifacts when applied t
 o incompressible and plastic materials. Our analysis identifies the root c
 ause of this issue as the inability to capture non-constant strain in the 
 thickness direction. Our new Q3T elements address this limitation with a m
 inimal yet effective modification to linear prisms, resulting in significa
 ntly improved performance with only a moderate increase in computational c
 ost. Through various examples, we demonstrate that our Q3T elements closel
 y match the qualitative behavior of reference simulations and provide accu
 rate quantitative results compared to real-world deep drawing experiments.
