Abstract

In this study, the relationship between dynamic MODULUS OF ELASTICITY derived from longitudinal VIBRATION method and static MODULUS OF ELASTICITY and bending strength in two directions: Parallel to machine direction and cross machine direction have been investigated.For this purpose, 4 PLATEs of particleboard with the dimensions of 124´90´1.6 cm (length´ width´thickness) were selected and free longitudinal VIBRATION test in PMD and MD were performed on each PLATEs. Then, the primary PLATEs were cut to four PLATEs with dimensions of 62´44´1.6 cm (length´width´ thickness) and longitudinal VIBRATION test in PMD and MD were performed on each PLATEs again. Finally, each PLATEs were cut to samples with the dimensions of 36´1.6´1.6 cm and longitudinal VIBRATION test and STATIC BENDING test were measured. The results showed good correlation between dynamic MODULUS OF ELASTICITY from longitudinal VIBRATION test and static MODULUS OF ELASTICITY and bending strength (result of beams extracted from each PLATEs) in both sizes of the PLATEs (in two size, 124´90´1.6 and 62´44´1.6 cm) and samples cut from each PLATEs in two directions (PMD and MD). In addition, there was good correlation between dynamic MODULUS OF ELASTICITY of longitudinal VIBRATION from two size PLATEs (124´901.6 and 62´44´1.6 cm). When the samples were smaller, the dynamic MODULUS OF ELASTICITY values were increased, due to the diffusion of waves in samples with larger dimensions. In general, according to results of this research it can be concluded that by applying the appropriate correction factors, longitudinal VIBRATION method can be an efficient method for calculation of dynamic and static MODULUS OF ELASTICITY and to estimate of the modulus of rupture in full size PLATEs.
