Quantitative stability estimate for the inverse coefficients problem in linear elasticity

H Meftahi,
T Rezgui

Abstract: In this article we consider the inverse problem of reconstructing piece-wise Lamé coefficients from boundary measurements. We reformulate the inverse problem into a minimization one using a Kohn-Vogelius type functional. We study the stability of the parameters when the jump of the discontinuity is perturbed. Using tools of shape calculus, we give a quantitative stability result for local optimal solution. Dans cet article, nous considérons le problème inverse de reconstruction des coefficients de … Show more
