摘要

•Plasticity and fracture of heat treated aluminum sheet is characterized.•New cruciform specimen is proposed that has proportional loading paths to fracture.•Fracture locus is determined by hybrid experimental-numerical method.•Plasticity modeling is critical for the fracture locus; Yld2004-18p criterion is used.
