A photoelastic determination of stress-intensity factors under thermal stresses
An experimental method for the determination of stress-intensity factors (SIF) at a crack tip under thermal loading is presented. The experimental technique used is thermophotoelasticity. Data were collected from whole-field patterns by means of a digital image analysis system. SIF values were extracted using the stress field equations obtained from Williams' stress function. The photoelastic fringe field corresponding to predicted SIFs was regenerated and superimposed onto the actual fringe field to verify the results. © 1990 Kluwer Academic Publishers.
