Abstract

We present a framework for parallel explicit dynamics simulation of frictional contact-impact problems involving shells and solids on distributed memory architectures. Contact detection is performed in parallel with orthogonal range queries based on a sparse bucket data structure. For contact enforcement a new algorithm is introduced, which exactly satisfies the kinematic impenetrability constraints and conserves linear and angular momenta. The versatility and efficiency of the proposed framework is demonstrated with selected thin-shell and solid applications.
