Abstract
The present work derives exact --- invariant --- solutions to the mode shape equation of uniform rectangular Kirchhoff plates via enhanced group analysis techniques. The study of the optimal system of the finite-dimensional Lie algebra of the admitted classical Lie point symmetries yields three nonequivalent invariant solutions to the studied equation. An additional invariant solution arises from nonclassical Lie point symmetries.
