摘要
针对弹塑性力学研究混凝土本构问题带来的不足和缺陷,运用损伤力学的方法,导出混凝土在单轴拉、压状态下的损伤表达式,得到了混凝土在弯曲状态下的统一的损伤演化方程。
Aiming at the shortages and demerits in the study of constitutive relationship of concrete based on elastic - plastic mechanics, damage expressions of concrete subjected to uniaxial tension - compression was deduced based on damage mechanics, and general damage evolution equation of concrete in bending state was received also.
