| Abstract: | Theories of static and dynamic constitutive model for concrete are outlined to provide tools of constitutive modelling for concrete.They include not only classical continuum mechanics,traditional elastoplastic theory and thermodynamics,but fracture mechanics,damage mechanics,micro-mesomechanics and endochronic theory developed recently.They are cornerstone and spirit for concrete constitutive modelling.They construct the framework of the concrete modelling together and make cocrete modelling fresh constantly.Some applications on concrete modelling are depicted.The trends of theoretic fundamentals of the concrete modelling are previewed. |
