| 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. |
