Titel
Assessment of local multiaxial stresses on a cast aluminium truck wheel under complex service loading and fatigue life evaluation
Abstract
The assessment of multiaxial stress states is already a very difficult subject for constant amplitude loading. If the stresses occur additionally at random, the assessment procedure becomes even more complex, because the design engineer is confronted with following problems like selection of the valid strength hypothesis by which the multiaxial stress state, especially for changing principal stress directions, has to be transformed into an equivalent uniaxial state and the application of the valid damage accumulation hypothesis for accounting of the stress spectrum. Especially, for safety components like wheels for which failures during service must be prevented, the challenge of the assessment procedure becomes obvious.
