| Abstract;An elastic stress formulation was expressed for the square tubular case (CFBS: anisotropic panel) of the corrugated fiber board box shape (width L, height h) under uniform compression py0 at centers in upper and lower edges. Then from this formulation the stress analysis is performed, and maximum values (.SIGMA.xmax, .SIGMA.ymax, .TAU.xyma, .SIGMA.1min, and .TAU.1max) for normal stresses .SIGMA.x and .SIGMA.y to width and height directions and shear stress .TAU.xy, principal stress .SIGMA.1 and principal shear stress .TAU.1 were obtained and characteristic behaviors for .SIGMA.xmax, .SIGMA.ymax, .TAU.xymax, .SIGMA.1min and .TAU.1max were discussed. Rates of values .SIGMA.x and .TAU.xy for the anisotropic case to the isotropic are about .NU.xy Ex/Ey and .SIGMA.ymin/(.SIGMA.ymin-.SIGMA.xmin) respectively. Ex and Ey are elongational elastic moduli in width and height directions and .NU.xy is Poisson's ratio (strain effect for height direction normal strain to width direction normal strain). Positions of .SIGMA.ymin and .SIGMA.1min are in the loading range of upper and lower edges and are independent of the case shape change, and .TAU.xymax and .TAU.1max change as be at positions of distance L/2 .+-. .DELTA.x from corners in upper and lower edges with increases of L and the loading range.
