ASTM D3044 Test for Shear Modulus of Wood Based Structural Panels

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D3044 testing. This standard covers the determination of the shear modulus of wood-based structural panels associated with shear distortion in the plane of the panels.

The method can be applied to any type of wood-based structural panel. The grain direction or orientation of the individual plies, laminations or layers should be parallel or perpendicular to the edge of the test specimen.

If the plies, laminations or layers have different material or elastic properties, the method gives the effective shear modulus. Wood-based structural panels used include plywood, oriented particleboard and veneer, and composites made of wood-based layers.

This test method is mainly designed for material where the grain or orientation of individual plies, laminations or layers is parallel or perpendicular to the edge of the sample. However, if using a four-ply panel with all plies the same thickness, it can be used for plywood samples where the grain is at 45° to the sample edges. The control condition is that the EI (modulus of elasticity × moment of inertia) values ​​along both diagonals are equal.

Values ​​stated in inch-pound units should be considered standard. Values ​​in parentheses are mathematical conversions to non-standard SI units, provided for informational purposes only.
