Concave laser forming and convex forming are all required for the complicated curved surface plate forming. Concave laser forming can be readily obtained by temperature gradient mechanism; while convex forming may be achieved based on buckling mechanism. To achieve precise control of bending direction of plate; buckling critical condition is analyzed when the buckling mechanism plays a dominant role; and a judgment criterion of working conditions of buckling mechanism; Fbuckling value; is derived. To verify the validity of the Fbuckling value; the experiments and numerical simulations are carried out. The results suggest that the bending direction of the plate can be exactly judged according to the Fbuckling value. In addition; the effects of the heating location and starting point on the bending direction are discussed; which provide further insight into the convex forming process and is helpful for the parameter selection of future process planning. © 2008 American Institute of Physics;
