Abstract
To maintain the continued airworthiness of civil and military aircraft it is essential that the fatigue behaviour of components subjected to complex multiaxial stress conditions be both understood and predicted. This topic is extremely complex and numerous criteria ranging from the purely empirical to the theoretical have been proposed. To this end it is necessary to know the localised stress–strain history. Whilst a detailed finite element analysis can be performed it is often very time consuming. Consequently, the present paper focuses on the development of a simple method which combines modern constitutive theory with either Neuber's, or Glinka's, approach to calculate the localised notch strains. Here particular attention is paid to the effects of cyclic loading, mean stress relaxation and its effect of fatigue damage.
