OPTICAL METHOD OF CAUSTICS - FULFILLED EXPERIMENTAL APPLICATION TO THE CONTACT PROBLEM

Damir Semenski

Abstract

Experimental optical method of caustics is established for solving the singularity at the crack tip through the stress intensity factor evaluation. Method is advantageously improved in application to mechanically anisotropic materials such as fiber-reinforced composites. Recently, the experiments are performed for different types of isotropic body contacts and the analysis of optical effects. Task of experiments is prediction of the future of inspected material surface and the assessment of structure damage. Theoretical fundamentals will prospectively provide the application of the method of caustics to the contact of the structural parts made of composites.
