MODELING OF LONGITUDINAL WAVES IN A SHELL WITH A PHYSICALLY QUADRATIC NONLINEARITY, FILLED WITH LIQUID AND ENVIRONED BY AN ELASTIC MEDIUM
This paper proposes an approach for modeling longitudinal strain waves in a cylindrical shell with physically quadratic nonlinearity and surrounded by an elastic medium. The generalized Gardner-Ostrovsky equation describing the solitary wave’s propagation was obtained by using the perturbation method.
