Such system is determined by a function $W$, called strain-energy function. We consider four forms of $W$ which are known in the literature. These are St.Venant-Kirchhoff, Ogden, Kirchhoff modified, Blatz-Ko-Ogden forms. In each of those cases we determine the conditions for the parameters $\\rho_0$, $\\mu $ and $\\lambda$, under which the corresponding system is hyperbolic and genuinely nonlinear. We also establish what it means a weak solution of an initial and boundary value problem.
