This study develops PERISOFT, a peridynamic (PD) simulation software, to overcome PD theory's high computational costs and limited engineering applications by coupling PD with classical continuum mechanics (CCM), enabling efficient simulation of material fracture, including crack initiation, propagation and branching.
Built on the GENVI platform, PERISOFT employs an adaptive PD-CCM coupling algorithm that dynamically transitions between local (CCM) and nonlocal (PD) domains based on stress strength or bond failure. It integrates four solving modes (finite element method (FEM), bond-broken induced peridynamic model (BIPD), strength-induced peridynamic (SIPD) and PD) to address static/dynamic problems.
Validation via representative case studies demonstrates PERISOFT's capability to accurately model complex fracture patterns and provide quantitative mechanical insights. Beyond serving as an analytical tool, the platform offers extensibility for further development of PD theory, making it relevant to researchers in computational mechanics, material science and fracture modeling.
As a PD software leveraging the GENVI platform, PERISOFT bridges PD theory and engineering practice. Its adaptive coupling algorithm and hybrid solving modes offer a novel, flexible framework for multiscale fracture analysis, advancing computational mechanics and material failure research.
