Elastic Wave Propagation In A Medium Containing Oriented Inclusions With A Changing Aspect Ratio: A Physical Model Study

Velocities of shear waves with different polarizations, as well as compressional-wave velocities, have been measured using a pulse transmission method in a series of physical models. The observations were made in a composite material filled with rubber inclusions, of variable aspect ratio, simulating cracks filled with a ‘weak’ material. The inclusions were oriented in a plane but distributed rand...
