Implementation of the Cohesive Crack Model with the Finite Particle Method for failure analysis of reinforced concrete beams

This study presents the implementation of a Cohesive/Overlapping Crack Model (COCM) integrated with the Finite Particle Method (FPM), a meshless numerical analysis technique grounded in vector mechanics.The FPM is widely acknowledged for its efficacy in addressing dynamic, nonlinear, and fracture-related challenges.The proposed combined model provides a robust framework for accurately capturing both tensile and compressive failure mechanisms in materials, including plain and reinforced concrete.To validate the mode l's capability, simulations of three-point bending specimens were conducted, demonstrating its effectiveness in representing the intricate fracture behavior of concrete structures.
