The scattering of harmonic elastic anti-plane shear waves by two collinear symmetric cracks in infinite long strip using the nonlocal theory (Q1582544)

The authors discuss scattering of anti-plane shear waves by two collinear symmetric cracks of finite length in an infinite strip using the non-local theory. The problem is reduced to a triple integral equation of the first kind. The solution is obtained by the Schmidt method, and numerical calculations are carried out. Contrary to the classical theory, it is inferred that the maximum dynamic shear stress occurs slightly away from the crack tip, and that there is no stress singularity at the crack tip.
