Inverse Density Problem for Linear Elasticity: Uniqueness from Local Measurements on a Partially Accessible Boundary

Yu Jia, Chengyu Wu, Jiaqing Yang

We consider the inverse boundary value problem in an elasticity system. It is proved that the density function and its derivatives at the boundary can be uniquely determined f…
