Using the energy criterion, a method of assessing the post-buckling behaviour of initially imperfect plates loaded axially along two mutually perpendicular directions is suggested. Six combinations of boundary conditions are considered and all the plates studied had their edges held straight inplane. For example, the initial surface of a simply supported plate W , , before any loads are applied, is assumed tobe given by W, = 6, sin prrxla sin qrrylb (1) where 6, is the amplitude of the initial imperfection; a, b are the length and width of the plate, with a = @/a);and p, q are the number of half wave lengths in the X and y direction...
