Whole-field automatic measurements of isochromatics and isoclinics in photoelastic coatings

研究成果: Conference contribution

摘要

A software SIMFOT has been used to generate isochromatics for some birefringent models. It was improved in order to simulate isochromatics in an infinite plate with a single elliptical hole. Stresses are applied at far boundaries of this plate in the direction of the ellipse minor axis. This minor dimension can be changed as necessary to approximate a line crack by a thin elliptical hole. Images from this plate are compared with images from an infinite plate with a single circular hole and presents good agreement when the relation minor axis/major axis approaches one. Formulas for the whole stress field in a direct way to be implemented in computer are presented in this paper.
