There exists a special class of solid media called soft media (or weakly compressible media), for which the inequality ┣>>┤ is satisfied (┣ and ┤ are the Lamé coefficients) [1-6]. Such media with very small shear stiffness are dynamically similar to liquids to a great extent and exhibit strongly a “water-like” characteristic and, therefore, are also associated with the name of “water-like” medi...
