In this blog post, we will be showcasing a fatigue assessment of a bicycle frame. This fatigue assessment will be against certain cyclic loading scenarios. Cyclic loading scenarios, typical for bicycle manufacturers, can include, pedaling forces, horizontal forces acting on the front fork and vertical load acting on the seat post.

In this post, we will be highlighting the main features of Simulia's fatigue prediction software, fe-safe. Fe safe performs both strain and stress based fatigue calculations, incorporating many different fatigue algorithms (uniaxial strain and stress based, biaxial strain and stress based, advanced thermomechanical fatigue, elastomer fatigue, fatigue of welds etc.). Last but not least, a fatigue calculation example will be shown. This concerns a notched plate under a cyclic fully reversing (tensile-compressive) load.
