A Multi-Time-Step Method for Partitioned Time Integration of Peridynamics

Peridynamics is a nonlocal reformulation of continuum mechanics that is suitable for representing deformations with discontinuities, see [1, 2] and the references therein. We extend the peridynamic formulation to allow the use of multiple time steps within a single problem domain by decomposing that domain into a number of smaller subdomains, where the critical regions of interest are solved using a small time step and the rest of the problem...
