17 February 1987 Determination Of Characteristic Parameters In Three Dimensional Photoelasticity
Author Affiliations +
In the process of determining the complete state of stress at a general point in a three dimensional photoelastic model (in a non-destructive or a semi-destructive manner), the concept of optically equivalent model plays a very important role. There are three parameters that define an optically equivalent model and these are termed as characteristic parameters. In this paper, first a survey is given of the direct and indirect methods used to determine the three characteristic parameters and then a new indirect method to deter-mine these parameters is presented. An algorithm has also been developed to determine the characteristic parameters unambiguously by the new method. The new method is verified experimentally and compared with theoretically determined characteristic parameters using Jones calculus.
