Projective dynamics with dry frictional contact [PDF]
ACM Transactions on Graphics, 2020 Projective dynamics was introduced a few years ago as a fast method to yield an approximate yet stable solution to the dynamics of nodal systems subject to stiff internal forces. Previous attempts to include contact forces in that framework considered adding a quadratic penalty energy to the global system, which however broke the simple - constant ...

An implicit frictional contact solver for adaptive cloth simulation
ACM Transactions on Graphics, 2018 Cloth dynamics plays an important role in the visual appearance of moving characters. Properly accounting for contact and friction is of utmost importance to avoid cloth-body and cloth-cloth penetration and to capture typical folding and stick-slip ...

Cohesive frictional-contact model for dynamic fracture simulations under compression
International Journal of Solids and Structures, 2018 In this study, a cohesive frictional-contact model is developed by integrating the cohesive zone model and the frictional-contact model to predict fracture behaviors under compression. In the cohesive zone model, a potential-based model, named as the PPR
