Buckling of a standing corrugated sandwich plate subjected to body force and terminal load

Abstract The global buckling behavior of a vertically standing corrugated sandwich plate subjected to body force and terminal load is analyzed through an improved first order zig-zag shear deformation theory, with the transverse shear effect of face sheets taken into account. When the face sheets are relatively thick and/or the sandwich plate has relatively large thickness to height ratios, the transverse shear effect of the face sheets affects significantly the critical buckling load. The effect becomes more obvious when body force rather than terminal load is applied on the clamped plates. The influence of geometric parameters on critical buckling parameters is also explored.
