Fundamentals of elasticity and strength of materials
A formula is valid only for the mechanical model from which it was derived. In weldments, nominal stress, structural stress, local notch, plasticity and residual stress must be distinguished. The IWE must know where simple statics ends and detailed assessment begins.

A formula is valid only for the mechanical model from which it was derived. In weldments, nominal stress, structural stress, local notch, plasticity and residual stress must be distinguished. The IWE must know where simple statics ends and detailed assessment begins.
Does the selected mechanical model represent the actual force flow, stiffness, geometry and failure mechanism to be prevented?
The same force creates different stress depending on area, geometry and eccentricity.
Forces divide according to relative member and joint stiffness, not merely weld length.
