Photoelastic determination of Mode I stress intensity factor

Abstract

Application to earher methods of analysis of photoelastic information in a single edge notch specimen subject to tensile loading to determine Mode I stress intensity factor brought into focus the constraints and the limitations of the earlier methods. In this investigation, a new approach called the constant method has been put forth. The results obtained by this method are compared along with the values determined by using the earlier approaches against the theoretical values of the boundarycollocatioo method. The method is quite reliable and the results are in fair agreement with the houndary collocation results.
