Elastic waves refer to the propagation of mechanical vibrations in materials that deform and regain their original shape after the disturbance. This phenomenon is a key concept in the field of solid mechanics and encompasses various types of waves, such as compression waves (longitudinal waves) and shear waves (transverse waves). Elastic waves play a crucial role in various fields of science and engineering, including earthquake seismology, non-destructive testing, and structural health monitoring. Researchers study the behavior of elastic waves in different materials to understand their properties, such as wave velocity, attenuation, and dispersion. This knowledge is essential for predicting and mitigating the impact of seismic events, detecting structural defects in materials, and improving the design of engineering structures. Overall, research on elastic waves helps to advance our understanding of the mechanics of materials and contributes to the development of innovative technologies for various applications.
