Using logarithmic circumferential strain definition
a nonlinear wave equation based on transverse axi-symmetrical motion of a elastic cylindrical shell in axial compression was derived.By means of the reductive perturbation method(RPT)
a nonlinear Schro。dinger equation was obtained.The exact periodic solutions of nonlinear wave equation was obtained by means of traveling wave method.The envelope solitary wave solution was given when the modulus was in degenerate case.The chaotic behavior of nonlinear Schro。dinger equation in a cylindrical shell subjected to axial compression were discussed under damping and external load perturbation.The threshold condition of the existence of chaos property under Smale horseshoe was given.It shows diversity and complexity of chaotic motion.
