3D Elliptical Crack Depth Estimation from 2D Surface Displacement Observation

Archive ouverte

Pineau, Pierre | Réthoré, Julien | Baietto, Marie-Christine | Fregonese, Marion

Edité par CCSD -

International audience. This paper presents a method to estimate the depth of an elliptical 3D crack from 2D observations on surface displacement fields. An iterative numerical procedure with leastsquares error minimisation is developped to compare pseudo-experimental displacements fields with a FEM displacement fields database and estimate crack depth.
