Abstract

In this paper, the stress singularity in homogenous material was studied using an optical experimental method. The study on stress concentration is of great research value to evaluate the damage inside materials. Coherent gradient sensing (CGS) is introduced to study the mechanical behavior of homogeneous material which was widely used in industry and research. The governing equations of CGS which is used to represent the optics-mechanics relation of the singular yield near the point of the external force are derived. The experimental result shows this CGS method as a nondestructive methodology is capable of estimating the load with high accuracy.
