This review was written as the German contribution to the ICAF-Minutes. It contains summarized results of investigations in the field of fatigue gained by industry and research organizations. Most of the subjects are fatigue test results from specimens and components under constant amplitude, program and random loading. Other reports concern investigations about the cyclic stressstrain behaviour as well as crack propagation, fracture mechanics and residual strength. A considerable number of reports on investigations of composite materials, especially of graphite/epoxies and their properties under environmental influence, are included. (-z-)
