【Abstract】 Key theories and approaches on establishing dynamic damage constitutive model for concrete are outlined,which include continuum mechanics,damage mechanics,classic plasticity mechanics,continuum thermodynamics containing internal variable theory,micro-mesomechanics and endochronic theory.Constructing scientific and reasonable dynamic damage model for concrete requires knowing those theories well.Brief description has been made on applications and their characteristics as well as shortcomings.The trends for these studies are previewed.更多还原
