There are some cases where the law of proportionality can not apply to the stress intensity factors of cracks under various geometrical, mechanical and physical conditions. As an example of such cases, the dynamic stress intensity factors are analyzed for a crack which is parallel to a plane boundary and impinged by a plane harmonic SH-wave. Consequently, it is made clear that the cracks embedded in specimens with same material constants and similar crack configurations have different values of normalized stress intensity factors, the values of the dynamic stress intensity factors divided by a standard value. That is, the values of the normalized stress intensity factors depend on the crack lengths, so that the law of proportionality is not applicable to stress intensity factors under the dynamic condition.
