Abstract Scope |
Cracking during forming processes near cut edges has been a major issue for the forming of advanced high strength steel sheets. The current understanding is limited by the complexity of the problem, which involves complex microstructures, stress states, and strain paths. The employment of more advanced methodologies is required to imitate and characterize the forming process of the cut edges. In this work, we have conducted in-situ uniaxial tension tests and bending tests to identify the origin of the crack initiation and the path of their propagation. Our findings provide guidelines for avoiding the edge cracking phenomenon during forming operations. |
