| Abstract: | This study presents the implementation of ordinary state-based peridynamic (OSB PD) analysis in a finite element framework using ANSYS, a commercial software. The novelty of the present PD formulation is its ability to accommodate nonuniform discretization of the PD solution domain, which may be crucial for the realistic modeling of complex structures. It enables the use of variable horizon while eliminating the need for surface and volumetric correction procedures. The PD governing equations are constructed by using MATRIX27, an element native to ANSYS. The PD bond breakage during the implicit solution of these equations is achieved through the EKILL option in ANSYS. The efficacy and robustness of the present PD approach are demonstrated by considering four distinct geometric configurations, each subjected to specific boundary conditions. The results from the present PD approach exhibit a good agreement with those obtained from traditional finite element method (FEM) and experimental data. [ABSTRACT FROM AUTHOR] |
