Abstract An overall introduction of a new method of evaluating SIF—Weight Function is given. This is used to trace the development of the surface crack in the nozzle' s out-corner. It can beobserved that WF can be used to analyze the surface crack of various shapes under various load. For general engineering questions, WF is fairly accurate and a good substitute of FEM.
