Problems solved by computational mechanics are becoming increasingly complex, involving diverse geometries, boundary conditions, and materials. Recent studies show that combining different numerical methodologies is one of the most effective approaches for advancing fracture simulation. In this context, this work presents the implementation of Peridynamics (PD) theory in the ANSYS LSDYNA finite element software, enabling the creation of hybrid models called PD-DYNA. PD is a nonlocal theory in which particles are connected to one another, forming a continuum representation. Since the theory is not based on classical continuum mechanics, fracture simulation occurs naturally through bond breakage. To assess the results, comparisons with reference problems using the Finite Element Method are carried out to verify the implementation, while benchmark cases are employed to validate the fracture behavior of brittle materials. The results highlight the computational efficiency and applicability of the proposed implementation in structural analyses. This work emphasizes the potential of integrating PD and LS-DYNA as an advanced tool for fracture analysis in material engineering, pointing toward promising applications in new materials, varied loading conditions, and three-dimensional problems.
