Longitudinal Shear Stress in Neck Seams from Shear Force

τ_{∥, Vz} = - \frac{V_{z} \cdot S_{y}}{I_{y} \cdot \sum a}

τ_∥,Vz	Longitudinal shear stress in the neck seams from shear force
V_z	Shear force
S_y	Static moment of the connected cross-section part
I_y	Second moment of area
∑a	Sum of all weld thicknesses connected to the considered part of the cross-section
