Abstract

In the study of welded structures of a 6000-type aluminium alloy, equivalent structures (simulated HAZ) are tested in fatigue under in-phase, out-of-phase biaxial loads in the High Cycle Fatigue regime. Several existing multiaxial fatigue criteria (Dang Van, K.; Findley; Matake; McDiarmid) are evaluated under Castem2000. The results of all simulations are compared one to another and to the test data. Some criteria (Dang Van, K. & McDiarmid) are found to be somewhat conservative. Moreover, the comparison of the critical plan or direction of simulations is compared to test results. The criterion of McDiarmid is found to work the best for in-phase loads, but the worst for out-of-phas
