Abstract
We present a novel refinement approach in peridynamics (PD). The proposed
approach takes advantage of the PD flexibility in choosing the shape of the horizon by
introducing multiple domains (with no intersections) to the nodes of the refinement zone.
We will show that no ghost forces are needed when changing the horizon sizes in both
subdomains. The approach is applied to both bond-based and state-based peridynamics and
verified for a simple wave propagation refinement problem illustrating the efficiency of
the method.
