Summary
Historicully, stress analysis used for component design
assames "ideal" materials, i.e. with isotropic,
homogeneous and uniform metallurgical properties.
We know that this is untrue, no matter how good
the design. As design cannot provide fo, defect-free
materials or components, ok appropriute defect tolerance
should be the aim of the designer. Hence the
concept of fuil-safe components has been introduced
fo, safety-critical purts. Automotive wheels, howeveF,
ure not considered fail-safe and fatigue lW
prediction techniques fo, these components need to
be improved in an endeavour to provide light-weight,
attractive, but still safe und durable wheels. This
applied approuch, where the proposed lW prediction
model employs relutionships given by Gerber und a
proposed lW prediction model derived from combining
aspects of lW prediction models according to
Collins und Juvinall & Marshek. The results show
good coruelation with that of uctual wheel
fatigue
data.
