This 4-hour course will cover fundamentals of cyclic loading and metal fatigue, including common definitions, an overview of cyclic plasticity principles, and different types of fatigue damage morphology. Additionally, fatigue damage summation methods and cycle counting will be discussed, and material properties required for fatigue assessments will be described. The technical basis for the VIII-2 fatigue evaluation methods, an overview of fatigue screening, and perspective on the legacy ASME Smooth Bar fatigue Method will be offered along with practical example problems.

Recommended Prerequisite: DBA I and DBA II
