【Abstract】 A theoretical analysis is presented for the snap_buckling behavior of dished shallow shells under axisymmetric distributed line loads. The second approximate formulae of elastic behavior of dished shallow shells with various boundary conditions are qiven, and effects of geometrical parameters γ,β and k on non_linear behavior are discussed.更多还原
