【Abstract】 The Boundary Integral Equation has been applied in photoelastieity. The first stress invariant and its derivative on the boundary both can be obtained from photoelastie data. The equation can be used to determine stress tensor of any inner point directly, even if the model is acted on by concentric forces The result shows that the photoelastie test contains full information about the stress tensors. Three examples illustrate the use of these equations.更多还原
