The superposition property of elastic wave's Doppler effect and the influence of relativistic time dilation and length contraction on elastic wave's Doppler effect are also discussed.

This paper obtained the temperature effect caused by heat of hydration in hollow thin pier by thermal-stress analysis, considering the change of elastic modulus followed by time.

In the past, salt formation is often regarded as an elastic or elastic-plastic body, and the effect of time is not taken into account.
