Introduction to the fundamentals of durability engineering

Understanding the fundamental behaviours of a system and its components is key when designing today’s competitive products or when troubleshooting unexpected issues.

A process called functional performance engineering is used to relate the product’s attributes to these fundamental behaviors during the product development phase.

This presentation gives you an introduction to the theory of the fundamentals of durability and fatigue life design, considered in the context of functional performance engineering. Via real-life examples of fatigue failure, the difference between durability and fatigue is explained, as well as the mechanisms behind crack initiation and propagation. The theory behind the S-N curve and rainflow counting further illustrates possible design strategies against fatigue.

The presentation is designed for anyone who wants to learn about the basic theory behind fatigue in order to more effectively resolve durability issues.

Get familiar with following topics :

• What is durability?
• What is fatigue?
• What is an S-N curve?
• Which parameters influence fatigue?
• How to design against fatigue?
