06aug2:00 pm3:00 pmWebinar: How Things Break: Metal fatigue and its effects


(Thursday) 2:00 pm - 3:00 pm

Event Details

In its time, The Versailles Rail Accident was the deadliest event to occur on the railways. The concept that materials could become “tired” was still relatively new and not well understood. Much of our current knowledge and methods regarding metal fatigue can be traced to this incident and the subsequent investigations.
This historically significant event will serve as the context for explaining various aspects of metal fatigue. In particular, the Stress Life Theory, Miner’s Rule, and stress concentration factors will be discussed. Finite element analysis will be employed to facilitate calculations and aid the discussions.
This is an interactive seminar. Questions and comments from the participants are welcome and encouraged.
At the conclusion of this course, attendees will be able to:
• Understand the Stress Life Theory of fatigue
• Perform Miner’s Rule Calculations
• Apply these methods to assess designs
Course Schedule (all times approximate):
• Background and Historical Context – 10 minutes
• Stress Life Theory of Fatigue – 15 minutes
• Cumulative Fatigue Damage and Miner’s Rule – 15 minutes
• Implementation – 20 minutes
