Показать описание
There are three well established methods for calculating fatigue; Stress Life, Strain Life, and Linear Elastic Fracture Mechanics. Each method is available in nCode GlyphWorks and nCode DesignLife and has a unique set of requirements and formulations. This video explores the differences of these methods and describe where they are most applicable.

Nice! Do you guys have available databses for composite materials (UD, wove, short-fiber)? How does the fiber direction is imported from the FE-model to account for the different failure mechanisms while doing the life-estimation? Thanks!.

I like very much nCode for fatigue analyses! it allows performing a good fatigue assessment quickly, even with huge spectra. The only weak point I have found is the graphical post-processing: it is not user friendly at all and especially it takes enormous time to refresh big FE models: 20 or 30 minutes waiting time for an Ansys model with 3 millions nodes.
