Why call a crack one dimensional when it has a width associated with it? A hole is more one dimensional.
Dave Now, cracks actually can be studied, are they predominantly monodimensional as it is probably desired- chennels or bidimensional, can cracking be controlled? It has much to do with metallurgy. Some experiments could be done with nanotubes- probably if the material of the walls is not relevant. If Ed is right, I will gladly apologize in any case. As I have shown inthe VUCA paper, we need ceratainties. Peter
