The Error Estimation of Approximating the Crack to Identify the Interfaces Crack in the Mobile's Wire

This paper is devoted to estimate the error resulting from approximating crack, i.e. approximating the support of the jump of crack in mobile's wire. This estimation is important to identify the interfaces crack which have been completed by using the derivation of Reciprocity Gap of this model. This derivation is based on the principle of Galerkin finite element method.
