Fracture Instability

Abstract It is postulated that fracture occurs in an elastic-plastic, nonwork-hardening material subject to pure shear when a critical shear strain is attained throughout a critical volume of material. This postulate is combined with the classical equations of plasticity to predict when cracking will initiate from a notch at nominal shear stresses below the yield stress, when the crack will become unstable on increase of stress, and when unstable cracking will occur if a notch is cut while a constant nominal stress is maintained. Tests on aluminum foil under biaxial tensile stress show results similar to those predicted by the theory.

Main Factor

In the process of plastic forming of metals, ductile fracture is an important factor influencing the improvement of forming limit of metals, while ductile fracture criteria can predict when and where ductile fracture occurs. Some conventional ductile fracture criteria based on mesoscopic void-damage and their application in different plastic forming of metals are introduced in this paper. And the ductile fracture criteria will be summarized into two categories: based on triaxial stress degree and based on maximum tensile stress. Because the triaxial stress degree and maximum tensile stress are a main factor deciding the occurrence of the ductile fracture.
