Question

1) When considering buckling by inplane force ,why strain energy term dosen't include the mid surface strain energy term??
2) And when considering buckling of plates under lateral + inplane force , How the energy method equation should be derived to find critical Load that lead to buckling? by the direct forces, due to displacement w onl s ttie shells sh ok one by forces well as beams and latter The wor y, then equals 2y dy (0.14) f the plate. The plate-strain energy owing tol bending is given by here A is the area of the pl dx d (3.44) n of the basic expressions derived in the preceding paragraphs is illus e discussion of a plate-buckling problem which follows. The plate is taken t rated ted to constant direct forces (Ni Nyuring bending just before it buckles

Explanation / Answer

Theory of Thin Plates for Laminates. Thin isotropic, orthotropic or ... the strains normal to the plate mid-surface are neglected (the plate thickness ... deflections of the plate can be consideredin terms of nonlinear geometrical .... Let us consider one rectangular ply of the laminate with principal axes of ortho- tropy 1
