Paper Abstract

A thermoelastic technique has been used for the appraisal of a recently proposed specimen for the determination of the edge-sliding mode stress intensity factor KII. A relationship between the received thermoelastic signal in the neighbourhood of a crack and the associated stress intensity factor is given. A method for the interpretation of the thermoelastic data is presented. Non-dimensional stress intensity factors, obtained from specimens with machined slots, are compared with those obtained from photoelastic and finite element analyses. For the edge slot there is good agreement; for the central slot there are appreciable differences.
