Elastic Isotropic Space and Perfect Compressible Fluid
摘要
A linear elastic isotropic material is characterized by the density \(\varrho \) and a couple of elastic constants: the Lamé elastic constants \(\lambda \) and \(\mu \), or Young’s modulus E and shear modulus G (\(G \equiv \mu \)), or the the bulk modulus B and Poisson’s ratio \(\nu \).
