Abstract

This paper examines the relationship between fracture mechanics and metal working processes. Cracking in bodies that have suffered gross plastic deformation is discussed, in particular, the manner in which the work of fracture decreases with increasing deformation. Experiments on ductile fracture were performed on deep-edge-notched tension specimens (with varying lengths of ligament) made from 0. 1% carbon steel, 16-gauge sheet in the as-received and cold-work conditions. Metalworking conditions were simulated so that generalised plastic yielding of the ligament always preceded the initiation of ductile tearing. Experimental results show that the specific essential work of fracture is a material constant independent of the geometry and cold working of the specimen. The specific work before fracture initiation ( omega //p**i) decreases with increasing prestrains.
