Perturbation of symmetries for super-long elastic slender rods
Keywords: super-long elastic slender rod,symmetry,perturbation,adiabatic invariant Abstract: This paper analyses perturbations of Noether symmetry, Lie symmetry, and form invariance for super-long elastic slender rod systems. Criterion and structure equations of the symmetries after disturbance are proposed. Considering perturbation of all infinitesimal generators, three types of adiabatic invariants induced by perturbation of symmetries for the system are obtained.
