Hello guys,
I need to model tunnel lining in abaqus 6.10. i'm guessing that its required to ;
1.reduce the modulus E of soil (relaxation) up to 40%- 50% (how can i do that in abaqus????)
2. active the lining (beam element+ assembled, am i right on assembly ?)
3. remove the soil using *MODEL CHANGE, REMOVE
i was wondering how can i model that ?
any help or suggestion greatly appreciated,
