Nonproportional biaxial fatigue of welded joints

The proportional and nonproportional high-cycle fatigue behavior of mild-steel, tube-to-plate welded specimens was studied. In-phase bending and torsion, constant-amplitude fatigue tests were used to define the weldment baseline material properties and also to serve as a comparison with out-of-phase tests. In-phase, combined bending-torsion experiments were conducted on the tube-to-plate specimen to simulate the common laboratory tests involving stationary loads on a beam. Out-of-phase combined bending-torsion loading paths were generated for a tube-to-plate specimen to simulate cyclic stress states typical of highway bridge beams subjected to a single passage of a vehicle.
