Seamless coupling of bond- and state-based peridynamic and finite element analyses

This study presents a variational approach to couple PeriDynamic (PD) and Finite Element (FE) analyses take advantage of their salient features. The PD FE domains share the same nodes along interface without an overlap region any constraint conditions. Therefore, this does not require morphing or blending function that facilitates coupling over transition zone. Although is general limited commercial software, interactions for bond-based (BB), ordinary state-based (OSB) non-ordinary (NOSB) are modeled with MATRIX27 elements native ANSYS, purpose demonstration. It framework perform BB, OSB NOSB coupled traditional elements. provides ability practicing engineers in industry integrating into based design tools. can boundary be completely embedded domain. resulting global system equations includes contributions arising from nodes. These solved simultaneously requiring iterative procedure through implicit methods. it direct (seamless) results free displacement kinks; thus, unphysical stress concentrations do appear near between regions. Its accuracy demonstrated by considering isotropic elastic plates subjected various types conditions under quasi-static dynamic loading Also, its crack propagation double cantilever beam three-point bend test specimens. PD-FE agree well those FEM all
