Discussion of fracture paper #37 - A Novel Approach Improving Mode I+III Cohesive Zone Modelling
The advantage of simplicity is that mechanics and physics can be understood and predicted just by using pen and paper. In the end, numerics may have to be used but then you should already have a pretty good idea of what happens. The other way around, starting with numerics and a limited toolbox of models will seldom lead to anything new.
