Design of Torsion Stress in Glued Joints

η_{x} = \frac{τ_{tor, x}}{f_{v, tor}} + \frac{τ_{x} + τ_{x, z}}{f_{R}} = \frac{\frac{3 \cdot n_{x, y}}{b (n - 1)}}{f_{v, tor}} + \frac{\frac{\frac{\partial n_{x}}{\partial x}}{n - 1} + τ_{xz}}{f_{R}} \leq 1

b	Board width
n	Number of board layers
n_xy	Shear in the layer plane
∂n_z / ∂x	Shear of board layers
τ_xz	Shear in the thickness direction
f_R	Rolling shear strength
f_v,tor	Torsional shear strength
