The finite element method vs the edge function method for linear fracture analysis

An investigation was performed to compare the Finite Element Method and the Edge Function Method for the solution of two dimensional linear elastic fracture problems. The comparison was made to determine whether one of the procedures had a distinct advantage over the other for fracture analysis. Although each method has minor advantages for the computation of specific quantities or the analysis of specific types of problems, there is no major advantage for either procedure which is immediately apparent. Because of the considerable investment which many organizations have already expended on developing a Finite Element capability, and the additional investment which would be required to implement the Edge Function Method the application of the Edge Function Method will probably be very limited.
