Physical Simulation of Environmentally Induced Thin Shell Deformation

Hsiao-yu Chen, Arnav Sastry, Wim M. van Rees, Etienne Vouga We present a physically accurate low-order elastic shell model that incorporates active material response to dynamically changing stimuli such as heat, moisture, and growth. Our continuous formulation of the geometrically non-linear elastic energy derives from the principles of differential geometry, and as such naturally incorporates […]

Mechanical Characterization of Structured Sheet Materials

Christian Schumacher, Steve Marschner, Markus Gross, Bernhard Thomaszewski We propose a comprehensive approach to characterizing the mechanical properties of structured sheet materials, i.e., planar rod networks whose mechanics and aesthetics are inextricably linked. We establish a connection between the complex mesoscopic deformation behavior of such structures and their macroscopic elastic properties through numerical homogenization. Our […]

Methodology for Assessing Mesh-Based Contact Point Methods

Kenny Erleben Computation of contact points is a critical sub-component of physics-based animation. The success and correctness of simulation results are very sensitive to the quality of the contact points. Hence, quality plays a critical role when comparing methods, and this is highly relevant for simulating objects with sharp edges. The importance of contact point […]

The Human Touch: Measuring Contact with Real Human Soft Tissues

D. K. Pai, A. Rothwell, P. Wyder-Hodge, A. Wick, Y. Fan, E. Larionov, D. Harrison, D. R. Neog, and C. Shing Simulating how the human body deforms in contact with clothing, wearables, and other objects is of central importance to many fields. However, the tissue material properties needed to accurately simulate real human bodies had […]
