Abstract

Fatigue design of structures for high temperature service resorts to modelling based on elasto-viscoplasticity constitutive laws. The new model describes complex anisothermal cyclic loadings, accounting for viscosity on a large range of strain. The new constitutive law that has been developed for nodular cast iron, is intended for the design of automotive parts for high temperature service.
