MODELISATION PAR ELEMENT FINIE D’UNE TECHNIQUE DE REPARATION COMBINEE

Abstract

The objective of the present study concerns a numerical modeling by the three-dimensional finite element method, the repair of metal structures presenting notch-type damage by a combined technique (stop hole / composite) repairs called hybrid technique. In this study the radius of the stop hole and other notch repairs configurations are highlighted. A complementarily was offer from the hybrid method and it increases the repair efficiency about 89% for the radius of 2mm.
