Abstract

This paper deals with a contact problem developed in a birefringent sphere loaded by a plan along its diameter. In mechanical systems, contacts between moving elements can give rise to high stresses that can cause damage. Several authors [1–5] have contributed to the understanding of contact problems. To improve the design and the durability, it is necessary to determine accurately the stress fields particularly in the neighborhood of the contact zones. The analyzed model consists of a birefringent deformable sphere loaded along its diameter by birefringent rigid plans. Stress fields are analyzed experimentally with plan polarized light and circularly polarized light; photoelastic fringes are used to calculate stresses. A finite elements analysis with Castem package allows calculating the stress fields. Comparison between the experimental solution and the finite element one shows good agreements.
