Abstract
An output least-squares type functional is employed to identify the Lam´ e parameters in linear elasticity. To be able to identify even the discontinuous Lam´ e parameters the regularization is performed by the BV-seminorm. Finite element discretization is used and convergence analysis is given. Numerical examples are given to show the feasibility of the approachFile in questo prodotto:
