Abstract:

This work analyses the influence of batch-to-batch variability on both strain hardening and ductile fracture behaviour of a 42CrMoS4 steel under cold forging conditions. Mechanical testing combined with full-field strain measurements and finite element simulations is used to characterise material response and fracture under different stress states. Batch-dependent hardening laws are identified, and ductile fracture initiation is described using the Hosford–Coulomb criterion, calibrated independently for each material batch. The identified fracture strains and fracture surfaces exhibit a measurable variability between batches, even for similar stress-state conditions. The results provide quantitative evidence of batch-dependent material behaviour relevant for forming simulations
