A novel cohesive crack model for concrete based on linear displacement patterns in the fracture process zone
The evolution of the fracture process zone (FPZ) in concrete beams of various sizes subjected to three-point bending tests was quantified using digital image correlation techniques. Based on the full-field deformation data, the FPZ length and crack-opening displacement (COD) were obtained. The results indicate that the...
