Abstract
This paper presents a novel fatigue analysis procedure for fibre-reinforced polymercomposite laminates composed of unidirectional (UD) laminae. It consists mainly of a layer-wise continuum mechanics approach on the macro scale which has been embedded in the commercial FE-code Abaqus® as a material routine for plane-stress applications. The concept contains a discontinuous quasi-static degradation approach and a continuous fatigue degradation approach. The discontinuous approach bases on Pucḱs [1] failure mode concept and therefore considers different failure modes and distinguishes between compressive and tensile loading. The continuous degradation is determined by an energy-based hypothesis, which, in contrast to other concepts, combines strength and stiffness degradation. The current, intermediate state of the concept is already tested and shows promising results.
