WebAbstract. While photoelastic-model analysis is an effective method to measure stresses, its practical use is limited to solving problems under well-defined loading conditions which can be successfully applied on a simulated basis to the model. Further, model analysis does not take into account such conditions as hidden material defects ... WebA birefringent coating of 300-micron average thickness was applied to the beam samples. The birefringent measurements were made using reflective PSAT. The shear stress concentration factor was evaluated from the maximum shear stress distribution profiles displayed by the concrete samples.
WebAbstract. It is known that birefringent coatings are a powerful experimental technique for the determination of surface strains of metals or other opaque bodies. In this paper the complete state of strain in such a coating is determined for an arbitrary one-dimensional variation of the displacement at the metal surface. WebThe method of birefringent coatings allows the evaluation of the strain distribution on …
