The dynamic buckling of elastic cylindrical shells subjected to axial load

The dynamic buckling of cylindrical shells subjected to axial impact has been discussed in this paper The dominant equations of dynamic buckling of the cylindrical shells and the boundary conditions of the wave front were derived by using Hamilton principle. The effect of stress wave is taken into account. The qualitative analysis on dominating equations shows that the value of dynamic parameter lambda set the characteristics of solution, and when lambda < 0 the buckling of the cylindrical shells occurs. The direct spreading determinant containing twin-parameter acquired the dynamic buckling load. The some other conclusions are also obtained.
