Abstract
This paper presents a new method which combines the boundary element method(BEM) and the photoelastic fringe pattern for stress analysis over the region of interest bounded by isochromatics and the body surface. Using this hybrid numerical-experimental method, we can obtain stress solution at selected locations without isoclinic data. According to the isochromatics, boundary stress information can be obtained, which is used in BEM. The result by the method is more accurate than that by regular BEM analysis where unreal boundary conditions are often presumed, such as displacement boundary conditions. The isochromatic fringe pattern supplies the actual specimen stress information, and therefore this method improves the calculated accuracy, besides also decreasing man work hours. The results presented compare well with theoretical or purely experimental solutions.
