Abstract

In this paper we investigate The shock between absolutely solid body and elastic bar, the solid body of mass M moved with at first speed Vo, it knocks elastic bar on the damper having the stiffness factor k. The another end of bar rely on the elastic solid pedestal. The bar is loaded by the visco-elastic friction force on surrounding face. The frist we constitute the equilibrium equation systems, after that we used the finite difference for time variable to change this equation to elliptic-equation, next by using finite element method with one level to solve approximative system. Finally, we show the numerical example with the angorithm installed by MATLAB.
