Abstract: | In this paper, a general digital picture processing and texture analysis for photoelasticity is developed. Overcoming some defects of references 2] and 3], it presents an effective method to analyse fringe patterns of the photoelasticity. By means of the trigonometric function relationship between the light intensity I and the image fringe order N, the equations of the fringe order N on brightness Z are deduced, and the mechanical parameters are thus obtained. We established a system of sigital picture processing and texture analysis for photoelasticity, which is called OYC-1 system. Finally, this system is checked with an example. It is found that the differences between measured results and the theoretical values are within 2.3 percent.This paper is supported by the science funds of the Academia Sinica. |
