The edgewise compression strength of corrugated board with different structural para- meters corresponding to the medium with different elasticity moduli and Poissons ratios was measured by tests. When a certain amount of materials were provided, the larger the quantity of the medium was, the thicker the paper was. The lon- gitudinal modulus of elasticity was always larger than the transverse modulus of elasticity; with the increase in the quan- tity of the medium of the same type, its longitudinal and transverse moduli of elasticity and shear modulus gradually in- creased. For the corrugated board with the same quantity of core papers and a different quantity of surface paper, the ed- gewise compression strength would increase with the increase in the quantity of surfac
