Fatigue and Damage Tolerance (DaDT)
This course will cover the use of stress-life and strain-life approaches to both low cycle and high cycle fatigue in aerospace applications. The Boeing Detail Fatigue Rating (DFR) method will be described in detail for use by Boeing suppliers and vendors. Material data and allowable will be described in addition to the statistics behind fatigue analysis and life testing to validate the design. Stress concentration determination and finite element methods will be described with real world engineering applications in aerospace.
This course will provide as an introduction into DaDT analysis with emphasis on principals behind the use of software tools such as Nasgro and AFGROW. Load cycle determination and cycle counting will be covered with supplied software tools. The use of finite element modeling and integrating the FEM output into the DaDT analysis will be covered in detail with recommended methods for both modeling and post processing.
