The aim of this paper is to demonstrate by numerical simulations and experimental tests, that for a ductile specimen S.E.N. (Single Edge Notch) loaded in the mode I, the plastic zone dimension can be revealed by the shadow optical method. Assuming that the plasticity affects the displacement field topology near the crack tip, one shows that the study of multiple caustic shapes makes it possible to evaluate the plastic zone dimension. So, the use of the shadow optical method can give an excellent tool for the plasticity evaluation of loaded cracked structures.
