To nonlinear dynamical processes for some piezo-electric and electrically conductive continuum media

In the first part, there are constructing an union form of three-dimensional (respect to spatial coordinates) nonlinear dynamical systems of partial differential equations (PDEs) which contains as particular cases Navier-Stokes' equations and system of PDE theory of elasticity and, if on continuum media acts electro-magnetic fields, Maxwell's dynamical systems too. In the second part, using an union form, there are discovered some nonlinear wave processes for elastic and piezo-electric and electrically conductive anisotropic elastic thin-walled structures.
