Abstract

This paper presents a detailed investigation of the evolution of temperature field at the tip of a stationary crack subjected to dynamic loading in two different types of steels. A high speed two-dimensional infrared camera was used to image the temperature fields at the crack tips. In a high strength maraging steel, the thermograms reveal the development of plastic zone and the process of crack initiation and propagation. In ductile HY100 steel, the thermograms are used to estimate the evolution of J integral and its critical value at crack initiation. The temperature images are also used to investigate the dominance of HRR field around the crack tip.
