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.
