Grain-Resolving Simulation of Mock-High-Explosives with Ratel Implicit MPM
Abstract: Ratel is a matrix-free, high-order, implicit finite element (FEM) and material point method (MPM) solid mechanics package. In this work, Ratel is used to simulate …
Addressing Numerical Challenges in Frictional Contact Simulation for Finite-Deformation Solid Mechanics
Abstract: The numerical simulation of contact phenomena in implicit, finite-deformation solid mechanics codes presents significant challenges due to the introduction of nonlinear …
The Algorithmic Development of a Fully Asynchronous Conjugate Gradient Method
Abstract: Decentralized computing environments (DCE), or environments, such as edge computing, which utilize spatially distributed, non-hierarchical, and potentially heterogeneous …
Using Decentralized Learning to Reduce Communication in Column-Partitioned, Multi-Agent Systems
Abstract: Multi-agent systems introduce new challenges to distributed computing, such as unreliability and a need for data localization, which require robust decentralized learning …
