Numerical and Experimental Photo Elastic Stress Analysis on a Epoxy Circular Disc

The main objective of the paper is to present elastic stress analysis on Epoxy circular disc. With the approach of theory of elasticity, the elastic stress distribution on the face of disc has been computed. To validate the stress distribution computed analytically , two specimen are prepared using photo elastic materials and tested them on a refractive poloariscope . The two specimens are circular disks . Stress are determined on disk by loading diametrically in polariscope. The experimental stress analysis is based on pattern, colour and counting of fringes obtained on the surface of disks when they are stressed in the prsence of Monochromatic lights of the polariscope. The stress distribution expressions are implemented in MATLAB and these qualities are being contrasted with the experimental qualities all together validate to Numerical method that we proposed in this paper.
