| Abstract: | The dynamic buckling of composite laminated columns impacted by a striking mass is investigated. The buckling governing equation with consideration of lateral shear effect is solved by finite difference method. The influence of striking mass,inital deflection,stress wave, lateral shear deformation on the critical impact velocity and buckling mode is mainly studied. |
