Abstract
Considerable efforts have recently been made on combining experimental and numerical techniques in a so called "hybrid" method for stress analysis. One of these techniques is combining photoelastic "experimental" data with the boundary element "numerical" method. Most of this work has centered on using the boundary element method to solve the potential problem (i.e., Laplace's equation) where external boundary conditions must be specified. The results are combined with the photoelastic isochromatic information to separate the principal stresses at any desired interior location. This thesis, however, concentrates on combining the photoelastic data with the elastostatic boundary element method. This is advantageou~ since the individual stress components at
any interior location can directly and more accurately be determined without the knowledge of the isochromatic information at those locations. A region of interest is selected as a closed contour for the elastostatic boundary element solution for the model. Boundary conditions are specified in terms of traction vectors, which are either zero on free boundaries or calculated from the photoelastic data after utilizing the shear difference method to separate the stresses. The ability to partition a section of geometry has an additional advantage, in that it may allow areas to be analyzed away from the actual loading area and thus improve accuracy.
