A Convex Formulation of Material Points and Rigid Bodies with GPU-Accelerated Async-Coupling for Interactive Simulation

Chang Yu, Wenxin Du, Zeshun Zong +3

We present a novel convex formulation that weakly couples the Material Point Method (MPM) with rigid body dynamics through frictional contact, optimized for efficient GPU paralleli…

The critical exponent for generalized doubly nonnegative matrices

Xuchen Han, Charles Johnson, Pietro Paparella

It is known that the critical exponent (CE) for conventional, continuous powers of -by- doubly nonnegative (DN) matrices is . Here, we consider the larger class of diago…
