The regularized extended finite element method allows simulating cracking processes in structures through a smooth transition from continuous to discontinuous regimes by regularizing the enriched kinematics, properly considering the mechanical work spent within the regularized discontinuity zone, and adopting a suitable crack tracking strategy. The applications pertain to a wide range of problems, from the simulation of coated inclusions to the delamination of fiber-reinforced-polymers reinforcements to the simulation of mixed-mode cracking in concrete and timber beams. The contribution aims to illustrate the most recent advances and emphasize the method's advantages over other transitioning procedures.
