A nonlocal interface approach to peridynamics exemplified by continuum‐kinematics‐inspired peridynamics

Abstract In this contribution, we present a novel approach on how to treat material interfaces in nonlocal models based peridynamics (PD) and particular continuum‐kinematics‐inspired (CPD), variationally consistent peridynamic formulation. Our method relies interface where the subdomains overlap. Within region, kinematic coupling of two constituents is enforced. The contact purely geometrical as interaction forces act only between points same material. We provide detailed description computational implementation within framework CPD, that principle applicable all formulations PD. A variety numerical examples for modeling bimaterial illustrate utility technique both two‐dimensional three‐dimensional problems, including at large deformations. model approaches local when nonlocality parameter, horizon size, decreased. proposed methodology offers viable alternative previous PD, which are essentially imposing mixture rules interfacial parameters.
