Abstract: Upon the theory of generalized characteristic curves, the non-dimensional kinematic equations for the motion of an orthogonal anisotropy circular cylindrical shell under axial impact are derived including the shear deformation and rotary inertia effect.The wave propagation problem of a cylindrical shell with finite length, acted by both axial impact and torsion, is calculated through numerical integration. The method in question is applicable to even more complicated model.
