Mesh size identification for cohesive fracture model based on experimentally calibrated FPZ length and FDEM simulation

Key Points

• Identifying appropriate mesh size enhances the accuracy of cohesive fracture simulations.
• Experimental calibration of the fracture process zone length serves as a foundational measurement.
• Finite difference element method analysis illustrates the effectiveness of the model through simulations.
• Further validation may be necessary to consolidate findings and broaden applicability.
