Fatigue of Structures and Materials
Learning Objective:To develop methods for characterizing fatigue resistance of materials and predicting cyclic lives of structural components; discuss approaches for preventing fatigue failures through materials selection, fatigue resistant design, and "fleet management" concepts. Both crack initiation (stress and strain based) and crack propagation (fracture mechanics) approaches are developed and compared. While general class concepts compare to a variety of structures, emphasis throughout is on aerospace applications.
