When the velocity proportion of longitudinal wave to transverse wave of a bed is distinctly different from that of another bed, the reflection factor will be changed with the variation of incident angle according to the elastic wave mechanics, which is the foundation of AVO theory.

In order to study the transmitting characteristics of ultrasonic guided wave in partly embedded guardrail post and select the suitable guided waves mode and frequency for inspecting post length,authors calculated and analyzed the guide wave group velocities,attenuation and dispersion in unembedded part and buried part of the posts respectively on the basis of elastic dynamics theory.

Using the three-dimensional theory of elastic dynamics,the dynamic response of elastic media in half-space is investigated and the analytic solutions are given.

Time-dependent problems play an important role in many engineering aspects, such as elastic dynamics, heat conduction etc.
