Fatigue & Fracture Expert

Mechanical fatigue is a VERY popular topic with the Ansys user community, with many engineers and designers attending our fatigue-related webinars over the past few years.

Luckily, all our fatigue-related webinars—as well as all recent webinars—are recorded and available anytime. Learn more about mechanical fatigue and how to use Ansys and nCode DesignLife to solve fatigue models in these webinars:

Mechanical fatigue needs to be considered in lots of engineering designs. However, calculating fatigue values usually requires several assumptions that require knowledge and expertise beyond the typical engineering domain. Also, fatigue failures may be due to unique operating conditions and may not show up for years, possibly causing a significant financial impact as well as a blow to the company’s reputation.
