Effect of in-Plane Shear Modulus of Elasticity on Buckling Strength of Paperboard Plates
Keywords:Plates, elastic stability, buckling, shear modulus, paper
AbstractIn previous research, a thin-plate theory was derived for analyzing corrugated fiberboard under edgewise compression and subjected to localized buckling. In this note, buckling formulas for thin paperboard plates characterized by an approximate in-plane shear modulus of elasticity are further generalized to allow for arbitrary levels of shear modulus. The results have applications in the design of paper products made of composite plates.
