This paper presents a new and relatively simple engineering method for calculating the stress intensity factors for small-to-medium cracks emanating from a notch under arbitrary loading. The formulation can be used in calculating the fatigue life of notched components as well as in the shape optimisation problems with durability constraints. Several examples are considered to demonstrate the advantages of the present method in comparison with both existing approximate approaches and finite element techniques.
