Abatrac&--This paper provides the proof that the stress intensity factors in modes I and II for a Griffith crack in an orthotropic elastic plate can be calculated using the summation principle. It is also shown how the s~etry and skew-seem principle can be applied to stress intensity factors. Finall

β¦ Synopsis
The principle of superposition as applied for stress intensity factors for different types of loading will be discussed. Using an energy formulation, it will be shown that stress intensity factors for different loading types are additive provided all loading types tend to open the crack. Negative part contributions to the stress intensity factor may also be superimposed if the associated loads tend to close the crack along the entire crack front.

Although there are many kinds of finite element method for determining the stress intensity factor, the problem is still very complicated because of the existence of the singularity at the crack tip. In this paper the superposition of the ordinary finite element method on the singularity terms is ap
