Un modello di danno anisotropo per il calcestruzzo soggetto a carichi ciclici pluriassiali: formulazione teorica e validazione sperimentale

An anisotropic damage model for concrete is proposed which is capable of describing the material behaviour both under static and cyclic uni- and triaxial load histories. The model is featured by two independent damage tensors which separately account for damage induced by tensile or compressive strains. This proposal is furtherly extended to simulate cumulation of damage and permanent strains during fatigue tests. Comparison between model response and available experimental results is encouraging. Finally, possible future extensions are outlined.
