A formulation of elastic deformation was expressed for side plates in the case (width L/height h = 1/22) of the corrugated fiberboard box shape (CFBS) supported by upper and lower edges under uniform compression loading. Then from this formulation, behaviors for stress and strain were discussed.
Normal stresses σx, σy, and strains εx, εy in width and height directions for the plate are symmetric to center lines of the width and the height, and shear stress τxy is anti-symmetric. And εx is mainly plus and εy is minus, and the maximum of εx is in upper and lower edges and the maximum of |εy| is at distance L/7 from the upper or the lower edge in side edges. The maximum value of εx is about 10% to the maximum value of |εy|. The maximum of |σx| is constant to increases of L and h, and the maximum of | σy| increases a small with L increase and decreases a small with h increase.The maximum of|τxy|decreases obviously with L increase and increases obviously with h increase. The maximum of εxfirst increases a small and next decreases obviously with L increase, and first increases obviously and next decreases obviously with h increase. The change of the maximum of |εy| is a small to changes of L and h.
