Titel

Nodular cast iron for normal and arctic temperatures in wind energy

Abstract
The present article discusses the cyclic material behavior in form of stress-life, strain-life and cyclic stress-strain curves of three different nodular cast iron materials derived by specimens taken from heavywalled cast blocks. Results are shown for static as well as cyclic stress and strain controlled tests performed at room temperature. Additionally, issues concerning the materials' behavior in low temperature application are also discussed through results gained by cyclic stress controlled tests at TH = -40 °C for alternating, R0=-1, and tensile loading, R0=0. For comparison, the corresponding static material values and the results of notch impact tests both at room temperature and TH = -40 °C are also given.
