Abstract
Elastodynamic stress concentration near the tips of a crack-like inclusion of finite length generated by the diffraction of high-freqency time-harmonic SH waves is analyzed. It is shown that the stress intensity factors at the tips of inclusion are provided by the fields describing the solution of the static boundary value problem for a semi-infinite strip and edge waves travelling between the two inclusion tips. The solution to the problem is expressed in a closed form that is computationally effective and yields accurate results in the resonance region of dimensionless wave numbers.
