It is proposed to determine damage fields on the surface of a material by using only full-field displacement measurements. A finite element approach is developed for which the unknown damage field is assumed to be piece-wise constant. Two examples are discussed in which the displacement field is either obtained by finite element analyses or measured by digital image correlation.
