“…Since the final strains involved far exceed strains at the elastic limit it is probable that elastic motion may conveniently be neglected. Cer-tainly the extension (to cylindrical shells) given by Vaughan [3] predicted results that were in very good agreement with experiment. However, the shells were of aluminum and final strains were upward of 10%.…”

“…The response (growth with time) of wn is examined for a range of values of n. It is possible to find a particular n which shows a strong preference to amplify and this value is taken as the theoretical buckling mode. This method has been used successfully in [3] to predict the response of cylindrical shells under axial impact.…”

“…To simplify the theory the strain rates were considered to be sustained at the constant values at the instant of impact. Vanghan [ 2] studied the same problem and did not assume the strain rates to be constant. An analysis, which predicts the number of waves so formed and also the value of V that produces waves of small amplitude, was developed in his study.…”

In the present paper, experimental studies on dynamic plastic buckling of circular cylindrical shells under axial impact are carried out. Hopkinson bar and drop hammer apparatus are used for dynamic loading. Three groups of circular cylindrical shells made of copper are tested under axial impact. From the experiments, the first critical velocity corresponding to the axi-symmetric buckling mode and the second critical velocity corresponding to the non-axisymmetric buckling mode are determined. The present results come close to those of second critical velocity given by Wang Ren [4~6]. Two different kinds of non-axisymmetric buckling modes oval-shaped and triangle shaped are founded. The buckling modes under two loading cases, viz. with small mass but high velocity and with large mass and low velocity using Hopkinson bar and drop hammer, are different. Their critical energies are also discussed.

“…[1][2][3][4][5][6][7][8], but no systematic research has been reported. Part of the difficulty stems from the experimental techniques, as discussed by Sasaki and Kurokawa [3] and a numerical calculation method is used here instead.…”
