Paper Abstract

Conventional methods of experimental stress analysis are often subject to limitations when applied to the prototype. Plant shut-down, careful component surface preparation, and lengthy test procedures are costly in time and lost production. The measurement of in-plane strains on the component under service environmental conditions is therefore very attractive. Holographic techniques show promise and in particular 'Electronic Speckle Pattern Interferometry' (ESPI) displays considerable potential as a non-contact method of measurement of in-plane strain on rotating components.
