摘要：

In this paper, the comparisons of modulus of elasticity MOE and resulting modulus of rupture MOR, determined using different dynamic and static testing methods is presented. Those consisted of amplitude resonance (dynamic MOE) method, two approaches of long span bending method, and industrial Metriguard machine stress rating method. All these non-destructive testing results were compared with standard 4-points bending testing MOE and MOR. The uncertainties of bending and 3-point ASTM Long Span tests were evaluated and uncertainty of Metriguard method was derived from calibration certificate for validation the interrelations of received models describing Lithuanian grown pine strength and stiffness.
