results of a numerical example show that this damage softening constitutive model for rocks can reflect the strain softening characteristic of rocks.
算例表明,该巖石损伤本构模型能反映巖石应变软化性状。
residual strain increases gradually and the increase rate becomes larger and larger with the increase in cycle, which means that damage softening effect appears.
随着循环次数的增加,残余应变逐渐增加,且增加的幅度亦有所加大,出现损伤软化的特征。
based on the above results, the damage softening statistical constitutive models for combined specimen with rock and shotcrete before and after freezing-thawing are established.
在此基础上,建立冻融前后组合试样的损伤软化统计本构模型。
