Research Abstract

Unstable crack growth under the quasi-static loading condition is studied experimentally and numerically. Images of the crack growth and the stress distribution around the growing crack tip, which is visualized by using photo-elastic technique, are successfully captured by the ultra-high-speed video camera with the frame rate of 1Mfps. Next, numerical algorithm to simulate the unstable crack growth is proposed in this work. The simulation result shows a good agreement with the experimental result, and it is shown that the proposed algorithm has the sufficient accuracy.
