Popis:	Six non-destructive test (NDT) techniques were studied for the stress determination for the long-term creep loading of wood based panels, determining the property as a whole (density and modulus of elasticity), across the thickness (maximum density and differential density) and along the transverse or longitudinal direction (flexural dynamic modulus of elasticity and ultrasonic modulus of elasticity) of board. The optimum alternatives to side matching method were derived and assessed by creep demonstration tests on particleboard (PB) and oriented strand board (OSB. The theoretical analysis and test results showed that the capability of new techniques for predicting the modulus of rupture (MOR) varies considerably, depending on the types of the density profile of the materials tested. The best correlation between actual MOR and predicted MOR by NDT techniques was achieved by combining the dynamic modulus of elasticity and density parameters for the materials with a type I density profiles (density ...
