Abstract

Daimler, with support from the Magna Powertrain Engineering Center Steyr, has developed a new method for the durability analysis of welds using nodal forces. It allows the mesh dependency of the analytically calculated stresses to be reduced and considers the most important geometrical parameters of the weld — for example, weld penetration and declination angle.
