Investigation of relationship between dynamic modulus of elasticity and static bending properties in particleboard plates
In this study the relationship between dynamic modulus of elasticity from longitudinal vibration method with static modulus of elasticity and bending strength in two directions: the Parallel machine direction and machine direction have been investigated. For this purpose 4 plates of particlebo...

In this study the relationship between dynamic modulus of elasticity from longitudinal vibration method with static modulus of elasticity and bending strength in two directions: the Parallel machine direction and machine direction have been investigated. For this purpose 4 plates of particleboard with dimensions 124× 90 ×1.6 cm (length× width× thickness) were selected and free longitudinal vibration test in PMD and MD were performed on each plates. After that the primary plates were cut to four plates with dimensions 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 the beams with dimensions 36× 1.6 ×1.6 cm and longitudinal vibration test and and static bending test were performed on them. The results show that 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 size of plates in two size (124× 90 ×1.6 and 62× 44 ×1.6 cm) and beams extracted from each plates in two directions (PMD and MD).
