DYNAMIC BUCKLING OF SHALLOW SPHERICAL CAPS SUBJECTED TO A NEARLY AXISYMMETRIC STEP PRESSURE LOAD

The behavior of shallow spherical caps subjected to axisymmetric and nearly axisymmetric step pressure loads is examined using a digital computer program for the geometrically nonlinear analysis of arbitrary loaded shells of revolution. A criterion for dynamic buckling under the nearly axisymmetric load is proposed and critical buckling pressures are determined for both loading conditions for a large range of cap sizes. A numerical convergence study is conducted to verify the accuracy of the results. (Author)
