Modulus of rigidity, dynamic plate shear, wood-based panels, torsional vibration


The modulus of rigidity of wood-based panels was measured by the dynamic plate shear method. This involves measuring the torsional vibration of free, square plates. The proposed equation to calculate modulus of rigidity was found to agree within ±5% of the experimentally determined values. The experimentally determined modulus of rigidity values were very close to moduli determined by other techniques.
