Paper Abstract

A method was presented for extracting isotropic points in structures using simulated isoclinics obtained from a combination of photoelastic experiments and finite element analysis (FEA). This method was divided into two parts. The first part involved the confirmation of the boundary condition necessary for FEA using isochromatics obtained by photoelastic experiments. The second part involved the determination of isotopic points using simulated isoclinics obtained by FEA under the boundary condition confirmed by photoelastic experiments. This method was applied to a ring a T-shape plates subjected to a compressive load. The results showed that the isotropic points in the ring and T- shape plates could be accurately and easily extracted by the method.
