[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 fi'\{!!3m^  
一般的程序都有这个功能 jiP^Hz"e  
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。 J pKCux  
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 ,zh4oX`>  
elastoplasticity between weakness planes. The proposed model combines the multilaminate "PC9[i  
model described in [1] and the general plastic yield surface of Men´etrey & Willam [2] and k9iB-=X?4s  
generalizes both. }Pj;9ivz  
The model’s performance is validated on selected benchmark problems and shows a good VP:9&?>G  
correlation with results available for comparison. The proposed model is believed to reproduce [\.@,Y0j
