| Abstract: | The impact buckling of a composite bars is investigated when one of its ends moves with a velocity due to axial impact compression. The shear effect is taken into account by treating the bar as a Timoshenko beam. The governing equation is solved by the finite difference method and the critical axial shortness is determined by the B-R criterion. The present attention is mainly focused on the effect of initial deflection,impact velocity and coupled stiffness. |
