In How Things Break: Fatigue, you'll learn ...

  • The basic mechanisms of fatigue failure

4 Easy Steps to Complete a PDHengineer webinar

Fatigue occurs when a material experiences repeated applications of a relatively low stress. Designers have long been aware that materials can become “tired,” and as early as 1829 Wilhem Augustus Julius Albert performed the first metal fatigue experiments in response to failures at the Clausthal Mines.

To this day, fatigue remains one of the leading causes of in-service component failure. Since fatigue failures can occur without warning, proper design is critical.

It’s important to understand the difference between failure and fatigue, so that’s where we begin the webinar. After establishing that difference, we’ll explore four design philosophies that engineers use when planning for fatigue:

  • Infinite Life Design
  • Safe Life Design
  • Fail Safe Design
  • Damage Tolerant Design

This webinar presents an overview of the material fatigue phenomenon, along with the methods used by engineers to estimate component life under cyclic loading.

The study is brought to life with several case studies presented to illustrate the concepts.

PDH credits

Webinars earn PDH credits for engineers in all states, unless otherwise stated in the literature for a specific webinar. For more details, check your state requirements.

ATTENTION NEW YORK, WISCONSIN AND IOWA ENGINEERS: Your states specifically require a certain number of "live" credit hours as a part of your PDH requirement. This webinar is provided by Decatur Professional Development, LLC and has been accepted by the New York State Board to fulfill this requirement. This webinars also meets the "live training" requirements of the Wisconsin and Iowa Boards.
