Abstract
This paper extends the discontinuous element insertion program (DEIP) to insert cohesive interface elements along periodic surfaces of representative volume elements (RVE). The key enabler involves zipping the RVE mesh along its periodic surfaces, generating a topologically closed grid similar to a torus. Such models are relevant to modeling grain boundary sliding and cracking in polycrystalline materials, for which a two-dimensional example is provided with hexagonal-shaped grains.
