Abstract

Highlights: Enhanced strategy to couple Peridynamics (PD) grids with the Finite Element meshes. FEM meshes and PD grids can have different characteristic lengths. The new coupling method has been applied to static and crack propagation problems. The presented coupling method is a solution to the "surface problem" of PD. Abstract: The paper presents a new and simple way to couple FEM meshes to Peridynamic grids with different grid sizes. The excellent performance of the coupling technique is illustrated by means of 2D examples involving rigid body motions, uniform strain conditions and a case of crack branching. The method paves the way to an increased use of peridynamics within FEM software.
