Abstract

Average elastic Von Mises equivalent stresses were calculated along the throat of a single lap fillet weld. The average elastic stresses were compared to initial yield as well as to plastic instability conditions to modify conventional design formulas so that they can be used to predict either extreme of failure by yielding. A new multiplying factor for the conventional design formulas is presented. The factor is a linear function of the thicknesses of the parent plates attached by the fillet weld.
