介绍了基于非线性弹性理论建立的不同本构模型的分析方法,给出并推导了模型中各变量的表达形式,以便描述混凝土在压缩范围内及破坏前的非线性变形,作为建立混凝土本构理论精确数学模型的基础.这些弹性模型必须与定义材料的破坏准则、定义压溃的断裂准则和"应变软化"混凝土在破坏后的应力转换结合起来.
Abstract：Based on the nonlinear elastic theory,different constitutive model methods were analyze and forms of each parameters in the models were derived,so as to describe nonlinear deformations of concrete in compression or before destruction and to establish a base for accurate mathematical models in concrete constitutive theory.Of course,the models must be associated with destruction rule of materials,cracking rule of crushing and stress transition of strain softening concrete after destruction.
