Elastic properties of particleboard as heterogeneous material

The investigations of elastic properties of the face and the core layer of particleboard are presented. The method of compressing the test specimens was employed. The electric resistance strain gauge technique was used to measure deformations of the test specimens. The board was treated as a plane isotropic material. The set of elastic constants, i.e. Young’s moduli, Poisson’s ratios and shear moduli were obtained. It was concluded that the particleboard layers are characterised by strong anisotropy of elastic properties.
