Summary

Almost no information on fatigue crack growth behavior of free-standing thin foils is available. Therefore, the objective of the present investigation was to develop a suitable testing method to investigate the crack growth behavior of thin metallic foils with thicknesses ranging from a few microns up to 200µm. Fatigue tests have been accompanied by the observation of dislocation structures due to plastic deformation in the vicinity of the crack. The size of the plastic zone in relation to the geometric dimensions have been studied for explanation of the fracture behavior. The applicability of the commonly used LEFM-based parameters is critically evaluated.
