Eulerian Solid Simulation With Contact
A new method for simulating realistic behavior of highly deformed, interacting solids without requiring explicit representation of the objects themselves.

Efficient Elasticity for Character Skinning With Contact and Collisions
A new and efficient algorithm for skinning skeleton-driven physically based elasticity. The algorithm and implementation are designed for efficiency with parallelism, matrix-free solvers, and branch-free vectorized and multi-threaded SVD computation. The paper demonstrates the system on real-world examples with contact and collisions.

Toward High-Quality Modal Contact Sound
This asynchronous mode-level-adaptive integrator with modified staggered projections synthesizes realistic multibody contact sounds. It resolves modal vibrations in both collision and frictional contact processing stages, thereby enabling non-rigid sound phenomena such as micro-collisions, vibrational energy exchange, and contact damping.

A Nonsmooth Newton Solver for Capturing Exact Coulomb Friction in Fiber Assemblies
This paper focuses on the challenging problem of simulating frictional contact between thin elastic rods. Following the seminal work by Alart and Curnier in contact mechanics, this work simultaneously models contact and exact Coulomb friction as a root-finding problem that can be simply solved using a nonsmooth Newton algorithm.

Large-Scale Dynamic Simulation of Highly Constrained Strands
A new framework for the simulation of constrained strands, which combines Lagrangian and Eulerian approaches. The two contributions are the reduced node, whose degrees of freedom precisely match the constraint, and the Eulerian node, which allows constraint handling that is independent of the initial discretization of the strand.
