In this case the rod, vibration could be described in terms of one-dimensional wave equation and a set of mechanical and ...Read more
Author:Shatalov, MDate:Jul 2011Many of wave propagation problems describing by hyperbolic equations could be formulated in terms of the variational principles. In the paper we demonstrate how to derive the systems of ordinary differential equations of the method of lines ...Read more
