摘要：

An axisymmetric elastodynamic finite element code has been developed that is capable of predicting quantitatively accurate displacement fields for elastic wave propagation in isotropic and transversely isotropic materials. The numerical algorithm incorporates viscous damping by adding a time-dependent tensor to Hooke's law. Amplitude comparisons are made between the geometric attenuation in the far field and the corresponding finite element predictions to investigate the quality and validity of the code. In addition, through-transmission experimental measurements made with a 1-MHz L-wave transducer attached to an aluminum sample support the code predictions.
