LARGE DEFLECTIONS OF SHALLOW CONICAL SHELLS UNDER CENTRALLY DISTRIBUTED PRESSURES

In this paper the deformations and stability in large axisymmetric deflections of shallow conical shells under centrally distributed pressures are investigated, The Newton-spline method for solving the nonlinear equations governing large axisymmetrie deflection of shallow conical shells is presentetd The buckling behavior is studied for a shell with fixed geometry when he size of the loaded area is allowed to vary, and for a fixed loaded area when the shell geometry is allowed to vary, Numerical results are given for v=0.3.
