3. Singular configurations
In this section, we take a look at some of the particular configurations in which the integral method can be effectively applied.

3.1.1 Singular elements
Some plate finite elements have been developed by integrating the stress concentration due to a crack (e.g. Robinson's 7-knot quadrangle). But integral methods are very efficient in this respect, precisely because the particular solution is singular.
Integral solid mechanics methods can also propose...
