NONLINEAR DYNAMICS OF HEMISPHERICAL SHELLS
The nonlinear dynamic response of a thin, clamped hemispherical shell subjected to a suddenly applied pressure is obtained. The governing fourth order, coupled, nonlinear equations are rewritten in finite difference form and the resulting matrix equation is partitioned into a form to which LU factorization can be readily applied. A "dynamic buckling" criterion is used, and both the axisymmetric and asymmetric responses are investigated.
