Abstract
Photo-elasticity used in various engineering fields in the past to investigate the stress distributions and concentrations, and it is the only method to visually observe stresses. However, this technique receives less attention nowadays due to the advances of numerical techniques and computational technology. The author utilized this technique to study the stress variations and distributions by considering typical conditions of slip of faults, discontinuities, slopes, foundations and underground openings in continuum and discontinuum and compared the stress states obtained from elastic finite element method. The authors present the outcomes of photo-elasticity experiments and finite element simulations. The results are compared with each other and their implications are discussed.
