This paper presents to study the resemblance and discrepancy between the rigid-plastic and elastic-plastic deformation of cantilever beams subjected to tip impact. For this, the theory of Ting's analysis  and calculation parameter obtained from Parkes  and Symonds and Fleming  are used for numerical computation. These results obtained from rigid-plastic deformation are compared with those results calculated by Reid and Gui  who used the non-linear finite-clement code ABAQUS for presenting the numerical solution of the elastic-plastic deformation of cantilever beams. No matter what rigid-plastic or elastic-plastic deformation, the kink phenomena of the plastic hinge arrest mechanism is all happen. The more the ratio of kinetic energy to fully plastic moment, the more kink phenomena. However, in the case of relationship between distance from root of cantilever and time, the position and time of plastic hinge happen in rigid-plastic deformation is difficult to predict while is easy for elastic-plastic deformation.
