Abstract


This article describes a new method for evaluation of radial crush strength of paper cores. Based on the theory of multilayered composites, a mathematical model has been developed to calculate the value of destructive force during radial crushing of spirally shaped paper cores whose layers are made of different materials. To start calculations it is necessary to have geometry parameters of the cores, Young's modulus and SCT of an individual component layers.
