Dynamic Stresses Due to Time-Harmonic Elastic Wave Incidence on Doubly Periodic Array of Penny-Shaped Cracks

Abstract: The symmetric frequency-domain problem of the interaction effects in rectangular lattice system of coplanar penny-shaped cracks located in an infinite elastic solid is numerically investigated. The problem is reduced to a boundary integral equation for the crack-opening-displacement in a unit cell by means of 3D periodic elastodynamic Green's function. This function is adopted for the effective calculation by its representation in the form of exponentially convergent Fourier integrals. A collocation method is … Show more

“…Investigate the possibility of using the considered accurate artificial grating of cracks are made in elastic material, for the organization of cutoff frequency ranges with the passage of the plane longitudinal wave. Use for this purpose the exact calculation according to the obtained formulas (14), based on the accurate numerical solution of auxiliary integral equation (15) and calculate the value H according to the formula (13). Obviously, cutoff frequency range occurs when the value of the transmission coefficient…”

“…The discussion is restricted to rectangular cracks and any finite number of parallel identical arrays. The topic of the problem is connected with [14,15] and some other published papers, but the mathematical technique is different. The wave process is harmonic in time, and all physical quantities contain the factor between the neighbor arrays.…”
