Dang Van multi axial safety factor anlysis


Dang Van is a multi-axial fatigue limit criterion and is a method of predicting the endurance limit under complex loading situations. The output from the analysis is expressed as a safety factor and not a fatigue life. It uses specific material parameters calculated from tensile and torsion tests. Manufacturing effects can also be accounted for by using equivalent plastic strain in the unloaded component.
Dang Van is primarily used for engine and powertrain-type applications where there are very large numbers of loading cycles of combined loading such as bending and torsion, producing multi-axial stress states.
