Physical basics of evaluating elastic characteristics of anisotropic composites by ultrasonic method

Resumo

As a result of analyzing the generalized Hooke law and wave equations for an anisotropic medium, computational expressions have been derived for evaluating the elastic constants of orthotropic, transversely isotropic, and isotropic media using the propagation velocities of longitudinal and shear elastic waves measured with the pulsed ultrasonic method in the corresponding directions.
