- 【Objective】In order to expand the applicable range of the free square plate when testing the principal shear modulus of wood, this paper proposes a new method for dynamically testing the shear modulus of wood, namely the free square plate torsional modal method.【Method】According to the unique first-order torsional mode characteristics and energy method of the wood free square plate, the relationship between the principal shear modulus of wood and the first-order torsional frequency of the free square plate is derived. First-order torsional modal frequencies of free-square plates were calculated using ANSYS for different tree species and different width-to-thickness ratios. Simulation and regression analysis were performed to obtain the modified equation between the principal directional shear modulus of wood and its first-order torsion frequency of the free-square plate（free-square plate torsion modal law equation）.【Result】The torsional mode characteristics of wood free slabs are divided into three categories
