Abstract

This paper begins by briefly discussing a simple method for calculating the stress intensity factors for cracks emanating from a notch under arbitrary loading. A range of examples are presented to demonstrate the accuracy of the present method. This technique is then used to extend existing design formulae for the composite repairs to cracks in thin metallic skins [J. Compos. Struct. 11 (1) (1989) 57; Int. J. Solid Struct. 17 (1981) 827] to allow for the repair of cracks at holes or notches under complex bi-axial loading.
