Experimental and Theoretical Investigation of Impact Dynamic Plasticity for CK45

The low velocity axial impact of thin-walled circular ck45 tubes is taken. The wrinkles develop progressively and the phenomenon is known as dynamic progressive buckling. In the present paper, experimental and theoretical studies on dynamic plastic buckling of circular cylindrical shells under axial...
