This lecture explains why, when and where fatigue problems may arise and the special significance to aluminium as structural material; it helps to understand the effects of material and loading parameters on fatigue; to appreciate the statistical nature of fatigue and its importance in data analysis, evaluation and use; it shows how to estimate fatigue life under service conditions of time-dependent, variable amplitude loading; how to estimate stresses acting in notches and welds with conceptual approaches other than nominal stress; it provides qualitative and quantitative information on the classification of welded details and allow for more sophisticated design procedures. Background in materials engineering, design and fatigue is required.
