Photoelastic Determination of Mixed Mode Stress Intensity Factors

A two dimensional finite model with inclined crack at different crack angles are being analyzed inmixed mode condition using photo elasticity method for the determination of stress intensityfactors. the well-known sih’s equation and three points deterministic approach is used for thedetermination of stress intensity factors. the effects of biaxial load factor, crack angle, size factorswere studied and a regression model was developed for geometry correction to predict stressintensity factors. the results give a good compromise to the theoretical one. the experimentalresult also gives significant data for the two dimensional mixed mode loading conditions.
