| Abstract: | In this paper the lateral unstability of alloy cantilever high beams are investigated experimentally under cylinder with plane ends impacting. The critical velocity and buckling modes of beams with 12 kinds of sizes are studied. It is found that somee dynamic character on lateral buckling different with the static ones. |
