Fatigue is a structural failure mode that must be recognized and understood to develop products that meet life cycle durability requirements. In the age of lightweighting, fatigue strength is an important vehicle design requirement as engineers struggle to meet stringent weight constraints without adversely impacting durability. This technical concept course introduces the fatigue failure mode and analysis methods. It explains the physics of material fatigue, including damage accumulation that may progress to product failure over time, and it provides the needed foundation to develop effective fatigue prediction capabilities.
Participants will investigate the assumptions and applicability of fatigue analysis methods, such as stress-life (SN), strain-life (EN), and crack growth. They’ll solve example problems by hand calculation, emphasizing and reinforcing the practical aspects of key concepts and methods in preparation for putting the knowledge into action.
Student computers are NOT required but may be useful for note taking.
By attending this seminar, you will be able to:
This course has been developed for engineers involved in design and development of structural parts and structural durability, including fatigue life prediction, improvement, or validation testing. It’s popular with both experienced analysis engineers and with those transitioning into a durability or analysis role.
The content is conceptual in nature, so it’s suitable for the broader engineering community. Engineering analysts will learn more about the durability-related tasks for which they are responsible. Product engineers and managers will learn key points about the durability concepts and analyses they need to understand to meet product durability requirements.
Participants should be engineers familiar with material behavior and general structural mechanics.
You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
Kurt Munson is the engineering manager at HBM Prenscia where he oversees software technical support, training, and engineering services in the fields of durability and reliability. He has 20 years’ hands-on experience in road load data collection, structural testing, and analysis, specializing in durability, fatigue, and vibration. He has a keen interest in the practical side of technical concepts and has been educating engineers on vibration and fatigue for 20 years. Kurt’s instructional goal is to communicate complicated technical concepts in a way that makes even less technical engineers more effective in creating durable, reliable products. He holds a bachelor’s degree in mechanical engineering from Michigan Technological University and a master’s degree in mechanical engineering from the University of Washington.
