Stress and Strain Estimation of Notches in Aircraft Structures
Abstract
To maintain the continued airworthiness of military aircraft it is essential that the fatigue behavior of components subjected to complex multi-axial stress conditions be both understood and predicted. This topic is extremely complex. Numerous fatigue failure criteria ranging from the purely empirical to the theoretical have been proposed. These criteria rely on the estimation of stress and strain at fatigue critical locations. This interim report focused on possible approaches which may be applicable to both low and high-cycle fatigue regimes. It discusses the relative advantages of the Neuber and the Glinka methods for calculating localized notch strains as compared to the results from finite element analysis.
