Peridigm is an open-source computational mechanics code based on peridynamics, a nonlocal extension of classical continuum mechanics that provides a consistent mathematical framework for modeling evolving discontinuities. Peridigm uses a particle representation to simulate large deformations and propagating cracks.
Peridigm is built on the Trilinos toolset and is suitable for massively parallel simulations. It has been exercised on models with tens of millions of degrees of freedom.
The principal differentiating characteristic of peridynamics is that it does not require specialization for the treatment of discontinuities. Instead, it directly incorporates phenomena, such as cracks, dislocations, voids, and grain boundaries.
Peridigm is publically available and is distributed under the BSD 3-Clause License.
