Symmetries and Fundamental Solutions of Displacement Equations for a Transversely Isotropic Elastic Medium

  • Alexander V. Aksenov
Part of the Understanding Complex Systems book series (UCS)


A fourth-order linear elliptic partial differential equation describing the displacements of a transversely isotropic linear elastic medium is considered. Its symmetries and the symmetries of an inhomogeneous equation with a delta function on the right-hand side are found. The latter symmetries are used to construct an invariant fundamental solution of the original equation in terms of elementary functions.
