A REVIEW ON THE CONSTITUTIVE MODEL FOR STATIC AND DYNAMIC DAMAGE OF CONCRETE
-
摘要:对混凝土材料在静力和动力载荷作用下的损伤本构关系模型进行了评述.梳理了混凝土本构关系研究的历史脉络和逻辑脉络;归纳总结了在混凝土本构关系研究发展过程中具有代表性意义、并且对重大工程建设具有参考意义的若干混凝土静力和动力损伤本构模型.基于对混凝土材料非线性及随机性的理解和诠释,阐述了混凝土静力和动力本构关系研究的发展趋势.Abstract:For the research ondynamic failure of major civil structures, constitutive modelingof concrete is one of its key scientific issues. The constitutivemodels of concrete subjected to static action or dynamicexcitation are reviewed in the present paper. The knowledge anddevelopment of constitutive models is discussed based on itshistorical developments and logical relations. Damage model ofconcrete which has been developed in recent years is summarized atmacro and micro levels. The development trends of constitutivemodeling for concrete are suggested on the basis of ourunderstanding of essential physical properties of concrete, e.g.its nonlinearity and randomness.
