Investigating the mechanical properties of paperboard ...

2020-10-13 · Corrugated paperboard is an orthotropic sandwich structure consisting of the surface plies known as liners, providing bending stiffness, sep-arated by a lightweight bending core (fluting) that provides shear stiffness (Figure 2). The machine direction (MD) and the cross direction (CD) are the two main directions charac-terising this material.

2021-7-17 · In torsion or bending, the stiffness decrease is more severe due to crushing, since the cardboard quickly recovers its crushed geometry (a trapezoid-like form). The more trapezoidal the form, the more the thickness decreases. Decreased thickness due to a small moment of inertia causes a high sensitivity of torsion and bending to crushing.
