An energy-based method for numerical fatigue analysis of carbon fiber reinforced plastic structures

This work describes experiments on multiaxial fibre reinforced plastic laminates, which were performed in order to create a model for the numerical fatigue analysis. To achieve this task fatigue tests of laminates with multidirectional layers submitted to constant and variable amplitude loading are analysed. The presented tests characterise the fatigue behaviour of carbon fibre reinforced plastics (CFRP) for unidirectional loading conditions and a chosen laminate. The specimens are analysed using light microscopy and computer tomography (CT).
