Developed a feature for the 4C-multiphysics/4C repository that enhances damage modeling fidelity in bond-based peridynamics by enabling pre-crack initialization. The work introduced parameters for defining pre-crack lines and planes, allowing the simulation to assign initial damage to bonds intersecting these geometries. This approach improves the accuracy of damage propagation modeling near cracks, laying the foundation for more realistic crack initiation scenarios. The implementation leveraged C++ and applied principles from computational physics, finite element analysis, and numerical methods. The contribution focused on core simulation logic, providing a targeted solution to model initial damage states in complex material systems.
