Abstract
The deformation properties of four different types of packing material used in compression testing — plywood, hardboard, fibreboard and particle board — have been tested in compression and combined shear and compression between steel plates used to simulate the lateral constraint experienced during a test. Additional tests with negligible lateral constraint were carried out to determine the Poisson’s ratios. Load deformation curves and relevant tangent and secant moduli are presented.
