Rotationally invariant viscoelastic medium with a non-symmetric stiffness matrix
The stiffness matrix of a viscoelastic medium is symmetric in the low-frequency-symmetric stiffness matrix in this paper. We determine the general form of a rotationally invariant non-symmetric stiffness <...

Representation theorem for viscoelastic waves with a non-symmetric stiffness matrix
In an elastic medium, it was proved that the stiffness tensor is symmetric with respect to the exchange of the first pair of indices and the second pair of indices, cijkl = cklij . The 6x6 stiffness matrix is thus symmetric...
