Prediction of sheared edge characteristics of advanced high strength steel

Abstract In the present work, numerical models are developed for shearing and cutting process of advanced high strength steel-blanks which can predict edge morphology in shear effected zone. A damage model, based on modified Mohr-Coulomb fracture surface, is calibrated. To increase predictability models, surface fine-tuned areas corresponding to stress-state cutting, a methodology called Local calibration Fracture Surface (LCFS). Four cases with varying clearance simulated verified experimental tests, showing good agreement. It thus found that suggested simulate adequate accuracy. Furthermore, it solely using plane-stress tensile specimens calibrating not enough obtain
