Elastic Wave Theory

Elastic wave theory describes how waves travel through solid materials when they deform elastically—that is, they temporarily change shape but return to their original form once the wave passes. These waves, such as seismic or ultrasonic waves, carry energy and information about the material's properties. The theory explains how the speed and behavior of these waves depend on factors like the material's stiffness and density. It’s fundamental in fields like geology, engineering, and materials science, helping us analyze structures, detect faults, or explore underground resources by understanding wave propagation in elastic materials.
