Advanced High Strength Steels (AHSS) play a critical role in the automotive industry due to their superior strength-to-weight ratio, enabling vehicle weight reduction while maintaining safety standards. However, their limited ductility and formability under complex loading conditions pose manufacturing challenges. Slide burnishing has emerged as a promising surface treatment technique to improve mechanical properties by inducing compressive residual stresses. In this context, the stretch-bending test is an effective method for evaluating fracture resistance in perforated AHSS sheets. This study investigates the influence of slide burnishing forces on the fracture displacement of two AHSS types: DP590-R and TRIP440-Y. An experimental design (32) was employed to evaluate the effect of three burnishing forces (125 N, 250 N, 400 N) and three punch diameters (3 mm, 6 mm, 12 mm) during stretch-bending tests. Numerical simulations using a finite element model with the Barlat anisotropic yield criterion accurately predicted thinning patterns near the hole, supporting experimental observations.
