Paper Abstract

Caustics technology is a powerful method to be applied in the analysis of cracks formation and growth. But the caustic curves seem very complicated and vary rapidly in the instant of the material fracture. In this paper, we develop a useful method to analyze the fringes of caustic, and improve them successfully in fracture testing. This method can be concluded by three steps: first, catch the image of caustic in the fracture mechanism by video camera, second, call the images out and process them with the new algorithm, and finally we obtain the fringe data from the computer.
