Crack Detection in Plane Semilinear ElasticityDang Duc Trong (1) National University, Hochiminh City, Vietnam
Let $\Omega$ be a two-dimensional semilinear elastic body limited by a known outer boundary $\Gamma$ represented by a Jordan curve and an unknown inner boundary $\gamma$ represented by a finite disjoint union of piecewise $C^1$ Jordan curves. Plane stress is considered. We assume that the Lamé coefficient depends on the spacial variables $x, y$ and the displacements $u, v$. Our main result asserts that $\gamma$ is uniquely determined by the displacements and stresses prescribed on an open portion $\Gamma_0$ of $\Gamma$.
