Peridynamics
Peridynamics (PD) is a new and innovative modeling technique that tracks non-local interactions between points within a geometry rather than a conventional mesh-based approach. This software models the interparticle coupling, called “bonds” within a moving region to reconstruct the local behavior and state of each particle, which offers many advantages over meshed solvers that require remeshing after deformation occurs. This framework allows for easy modeling of material removal, plastic behavior, and local damage, enabling extremely accurate predictions of crack formation and propagation, corrosion damage evolution, and high-displacement mechanical behavior.
