Let ­ be a two-dimensional semilinear elastic body limited by a known outer boundary represented by a Jordan curve and an unknown inner boundary represented by a finite disjoint union of piecewise Jordan curves. Plane stress is considered. We assume that the Lamé coefficient depends on the spacial variables and the displacements . Our main result asserts that is uniquely determined by the displacements and stresses prescribed on an open portion of .
