Paper Abstract

A non-contact and non-destructive method for full-field in-plane strain measurements has been developed. Digital image processing is employed for monitoring the deformations of gird liens marked ona planar surface of a component or a specimen. Full-field in- plane strain distributions are obtained by processing the geometrical characteristics of the grid with computer graphics algorithms. The applications and the future evolution of this method are discussed.
