Hallöchen!
I try to model crack propagation in thin film with sfepy. I must
admit that I don't understand everything in the docs because my FEM
knowledge is mediocre at best, but my plan is the following:
1. I take the "Linear Elasticity" example as a starting point (2.5.1
in the manual)
2. I substitute my own mesh and regions, and boundary conditions
3. I solve the problem
4. I look at the tensions between the nodes. If they exceed a certain
threshold, the respective connection breaks up. I change the mesh
accordingly.
5. I repeat 3 to 4 until no connections have to be broken up anymore
Is this a sensible approach?
