Une approche non destructive pour l'identification de contraintes de contact

Abstract

This note presents a nondestructive method for the identification of contact stresses between a rigid punch and an elastic half-space from measurements of normal displacements and tangential strains on the traction-free part of the surface. Numerical results obtained on axisymmetric sample problems validate the identification method, even in the presence of imperfect data and when the contact zone is not exactly known a priori.
