Paper Title:
Nondestructive Testing of Mechanical Properties of Pine Laminated Veneer Lumber
  Abstract

Laminated Veneer Lumber (LVL) panels made from pine (Pinus sylvestris L. Var. mongolica Litven.) veneers were tested for mechanical properties and prediction models in this study. Three different nondestructive testing (NDT) methods and the static bending test were conducted on the LVL. The NDT methods included the longitudinal vibration method, longitudinal transmission method and flexural vibration method. The effects of veneer thickness on the dynamic Young’s modulus and the modulus of elasticity (MOE) of pine LVL with vertical load were investigated. There were four variety thickness veneers including 2.2 mm, 2.6 mm, 3.0 mm and 3.4 mm. The results showed that the dynamic Young’s modulus and MOE of LVL diminished with the increase of veneer thickness, there was a strong linearity correlation between each dynamic Young’s modulus and the static MOE, and the prediction models of mechanical properties can be used to predict MOE of pine LVL.
