Abstract
The existence of wedge acoustic modes of a special fluidic type in solids is demonstrated using the ray theory of slow Krauklis-wave propagation in a fluid-filled wedge-shaped crack. It is found that the phase velocities of the modes at small crack opening angles are proportional to the square root of the angle. The number of localized modes in the semi-infinite crack model is not limited.
