Single specimen methodology for elasto-viscoplastic fatigue model identification of martensitic steels

Abstract : Cyclic constitutive models describing the fatigue behaviour of martensitic steels need the determination of numerous parameters depending on temperature and microstructure, Reduction of time and cost of this work is achieved through an integrated test and identification methodology based on a single specimen for each temperature and microstructure. Test procedure and identification strategy is described. Methodology is applied to a martensitic steel for different Rockwell hardness. Accuracy of the parameters is validated by comparing cyclic test results and numerical model predictions.
