Topological derivative for the inverse scattering of elastic waves
Topological derivative for the inverse scattering of elastic waves
To establish an alternative analytical framework for the elasticāwave imaging of underground cavities, the focus of this study is an extension of the concept of topological derivative, rooted in elastostatics and shape optimization, to threeādimensional elastodynamics involving semiāinfinite and infinite solids. The main result of the proposed boundary integral approach ā¦
