Abstract
The purpose of this paper is to define a low cycle fatigue criterion in ord er to predict the failure of engineering structures. The major problem in d efining a predictive fatigue criterion is that it should be applicable for structures submitted to complex multiaxial thermo-mechanical loadings but s hould be identifiable from simple experiments on specimens. After a short c ritical review of the principal criteria used in low cycle fatigue it will be shown that the dissipated energy per cycle permits a correlation of isot hermal and anisothermal results obtained on silicon molybdenum cast: iron i n the case of specimens and also on structures.
