Hi _lobo,
thank you for your inquiry.
When performing a nonlinear stability analysis, failure criteria are defined in the model itself, e.g. by using
- nonlinear material models (requires add-on Nonlinear Material Behaviour)
- nonlinear member/line hinges
- nonlinear supports (e.g. failure under tension)
- nonlinear stiffness types for main objects (e.g. tension member, membrane surface)
Next week there's be a webinar that will tackle this topic:
If you have any further questions, just ask. I'm happy to help
Best regards
