A Design Study in Crack Patching,

Abstract

A numerical investigation into the behaviour of cracked sheets which are patched with an overlay of composite material, is presented. This study gives guidelines as to the optimum location, size, and shape of patches. The main considerations are: reduction in the stress intensity factors at the crack tip, the maximum fibre stress in the patch and the maximum shear stress in the adhesive bond between patch and sheet.
