Paper Abstract

This paper describes a methodology that uses the frozen stress method of photoelasticity, with appropriate algorithms, for extracting the field strengths of the three local modes of crack tip deformation (K1, K2, K3) from a cracked photoelastic model. A part-circular crack in a large plate and a circum-ferentially cracked torsion bar are used to illustrate the application of the method. The accuracy of the results is estimated.
