Abstract

Physical properties (E_x, E_y, G_xy, V_xy) are necessary for analyzing the plane problems and fracture mechanics of orthotropic material, and measurements of physical properties and stress fringe values (f_x, f_y, f_xy) of orthotropic material are needed for each photoelastic experiment on orthotropic material. Strain gauges are generally used to measure the physical properties of orthotropic material, but errors due to various factors are common. Therefore, relationships between physical properties and stress fringe values are suggested in this paper. These can be utilized instead of the strain gauge to measure physical properties with stress fringe values. This is confirmed by experimentation in this study. Spemimens of CD are better those of BM for measurement of the stress fringe value of an orthotropic material. The stress fringe value f_xy can be obtained from Eq. (19) with f_x, f_y, f_θ and θ; in this case, θis between 40°and 65°. The optimum value is θ=45°.
