ABSTRACT:
A method and apparatus for testing shear stiffness in board is disclosed. The board sample (6) is placed into stationary jaw (2) and jaw (3) which is rigidly connected to inertial mass (7). The mass (7) is twisted around the sample axis with an initial twist chosen to ensure the sample is within the elastic region, and then allowed to freely oscillate. The oscillation frequency is then measured to evaluate the torsional stiffness of the sample.
