Abstract: This paper is concerned with modeling of fracture-based forming limit criteria for anisotropic materials in sheet metal forming to predict the sudden fracture in complicated forming processes. The Lou–Huh ductile fracture criterion is modified using… read more here.

DOI: 10.1063/1.5034762
Abstract: Inhomogeneous serrated plastic flow and the subsequent fracture of a Zr-based metallic glass are probed by high-speed in-situ pyrometry and in-situ acoustic emission. Whilst the temperature rise during serrated flow remains below the detection threshold… read more here.
