Abstract

In this work, a dual illumination beam system is used to obtain the stress intensity factor in modes one (mode $I)$ to mechanical elements during tension testing. The displacement field is obtained by means of electronic speckle pattern interferometry and phase stepping technique. Deformations are calculated by the Stokes differentiation method. Results are compared with a numerical simulation using a finite element analysis technique.
