Description of transient material behaviour under constant and variable amplitude loading for cold formed steels by linear flow splitting

This work aims to give a better understanding of the cyclic material behavior of linear flow split flanges of the steel HC340LA under constant and variable amplitude (spectrum) loading. The determination of the cyclic material behavior is of fundamental importance for exploiting of the lightweight potential of such profiles and the consideration of the transient material behavior plays a fundamental role for a reliable fatigue life estimation.
