SOME CHARACTERISTICS OF THE FRACTURE STRESS CURVE IN STEEL

The characteristics of both fracture stress curves, cleavage and fibrous, were investigated in regard to their dependences on temperature and stress-triaxiality. Used for experiments are a killed mild steel and high tensile strength steel. As the results of the experiments, the following important information is obtained. (1) The cleavage fracture stress curve is hardly affected by changes in temperature and stress-triaxiality, while the fibrous fracture stress curve is remarkably sensitive to those changes. (2) The condition for fibrous fracture is represented by one stress curve in the coordinates of the octahedral shearing stress and strain, regardless of the degree of stress-triaxiality. (3) A relationship was found for structural steels between the height of both fracture stress curves and transition temperature in V-Charpy test.
