Abstract
The aim of the present work is to investigate the softening behavior of a notched concrete beam under a three-point bending test analytically, experimentally, and numerically using XFEM in Abaqus. This study presented a trilinear stress-strain softening curve-based analytical model to describe the complete flexural behavior of plain concrete beams. The article also provides the mathematical equations necessary for calculating the force-crack opening displacement during all cracking phases until failure. An inverse analysis of the force-CMOD curves obtained experimentally has optimized the parameters required for the identification of the tensile stress-crack opening relationship. The ABAQUS environment was used for numerical modeling using the extended finite element method (XFEM), and a good agreement between the experimental and numerical results has been noticed.
