Numerical Study On Dynamic Buckling Of Composite Cylindrical Shell With One Edge Simply Supported And Opposite Edge Clamped

Considering stress wave effect, axial inertia and rotational inertia are calculated, and dynamic buckling control equation of cylinder shell is obtained by Hamilton principle based on the Donnell thin shell theory. The dimensionless of the equation is solved by differential method, which discuss about effects of different initial imperfection, different impact mass, different impact speed and different lay-up angle on the buckling of cylindrical composite shell. The result shows significant effects of stress wave and axial inertia on dynamic buckling.
