     A BOUNDING SURFACE MODEL FOR CONCRETE CONSTITUTIVE RELATIONSHIP
     混凝土本构关系边界面模型
短句来源
     ① On the aspect of application to the concrete constitutive models, the constitutive models used in finite element programs are simple and applicable. Nevertheless, these programs are all based on the models in stress space, but neither on the plastic theory in strain space which can simulate the phenomena of strain softening nor on the basis of damage mechanics to reflect the failure mechanism of concrete.
     ①在混凝土本构模型应用方面,大型商业有限元程序中使用的本构关系较简单实用,但这些软件仍是基于应力空间的本构关系,没有利用基于应变空间的塑性理论准确模拟混凝土“应变软化”现象,也没有利用真正意义损伤力学理论来反映混凝土的破坏机理,这对于模拟混凝土软化段有很多不足,需要进一步改进混凝土本构模型。
