摘要

摘要: 针对侵彻、爆炸等强动载作用下混凝土类结构计算中涉及的状态方程、变形破坏弹塑性本构关系与强度准则等关键问题，根据混凝土多组分特征，简述考虑介质中孔隙压缩的状态模型及弹塑性变形破坏中动态损伤演化模型，并在计算实验方法的基础上，给出需要进一步研究的建议。

Abstract: Based on several key issues of the elastic-plastic constitutive model, the equation of state and strength criterion, and the calculation of the strength of concrete under blast and impact loading were reviewed. Concrete being viewed as a binary material composed of matrix and pores, a model including the pore compaction and dynamic damage evolution in elastic-plastic deformation and failure were introduced. On the basis of a mathematical-experimental method, some conclusions and proposals for further reseach were made at the end of the paper.
