The Peridigm Meshfree Peridynamics Code

Abstract

Peridigm is a meshfree peridynamics code written in C++ for use on large-scale parallel computers. It was originally developed at Sandia National Laboratories and is currently managed as an open-source, community driven software project. Its primary features include bond-based, state-based, and non-ordinary state-based constitutive models, bond failure laws, contact, and support for explicit and implicit time integration. To date, Peridigm has been used primarily by methods developers focused on solid mechanics and material failure. Peridigm utilizes foundational software components from Sandia’s Trilinos project and was designed for extensibility. This paper provides an overview of the solution methods implemented in Peridigm, a discussion of its software infrastructure, and demonstrates the use of Peridigm for the solution of several example problems.

Why develop twice? Integration of continuum mechanical material models in Peridynamics

“…Given Peridynamics' focus on analyzing crack propagation processes, mesh-free methods are commonly employed for numerical solving. One of the advanced frameworks in this domain is Peridigm, developed by Sandia National Labs [4,5]. This framework facilitates parallelization of large-scale models and includes a post-processing interface to the open-source software ParaView 1 .…”
