Equivalent Domain Integral for Delamination Growth Estimation
It is known that delaminations are the most frequent causes of failure in laminated structures, particularly under compressive loads. The presence of delaminations leads to a reduction in the overall strength ...

Expert systems and finite element structural analysis — a review
Finite element analysis of many engineering systems is practised more as an art than as a science. It involves high level expertise (analytical as well as heuristic) regarding problem modelling (e.g. problem s...
