Acoustic bulletin, Vol. 15 ¹ 4, (2012) |
| A plane time-harmonic SH-wave propagation in an unbounded medium containing the randomly distributed fibers with interface cracks is investigated. The Foldy's approximation is applied to estimate the effective (average) dynamic parameters of such composites. The influence of the fiber shape, debonding (interface crack) sizes and direction of waves propagation on their effective phase velocities and attenuation coefficients are analyzed. |
