在对裂隙与孔隙、微裂隙两类不同层次损伤的演化特征与相互关系进行试验研究与分析的基础上,分别确定了表征这两类损伤的奇异损伤变量和分布损伤变量,推导了单轴压缩条件下非贯通裂隙介质损伤本构方程,并运用试验结果对其进行了验证。
Based on the analysis of relationship between damage evolution of crack and evolution of micro-crack, singularity damage variable and distribution damage variable have been defined, which can illustrate two kinds of damages, and the damage constitutive equation of non-interpenetrated crack material under uniaxial compressive condition has been built and validated by tests.
