[求助]有关岩石卸荷模拟的软件 [复制链接]

我想咨询一下各位，如果做岩石隧道围岩卸载应变的数值模拟，选用什么软件比较好？对模拟软件要求：（1）能够选择和输入特殊的破坏准则；（2）能够反映岩体在破坏后的体积应变、轴向应变和切向应变。

（1）能够选择和输入特殊的破坏准则 N^L@MR-  
一般的程序都有这个功能 fkV@3sj  
2）能够反映岩体在破坏后的体积应变、轴向应变和切向应变。 7Uenr9)M  
应该是个应变软化形模型，不知道这个本构是否适合你？你自己可以看一下。

We describe in this article a modified multilaminate model which takes into account matrix ;+Jx,{)

generalizes both. 8!
