| description | Multiaxial high cycle fatigue is a topic that concerns nearly all industrial domains. In recent years, a
great deal of recommendations how to address problems with multiaxial fatigue life time estimation have been
made and a huge progress in the field has been achieved. Until now, however, no universal criterion for
multiaxial fatigue has been proposed. Addressing this situation, this paper offers a design of a new multiaxial
criterion for high cycle fatigue. This criterion is based on critical plane search. Damage parameter consists of a
combination of normal and shear stresses on a critical plane (which is a plane with maximal shear stress
amplitude). Material parameters used in proposed criterion are obtained from torsion and axial S-N curves.
Proposed criterion correctly calculates life time for boundary loading condition (pure torsion and pure axial
loading). Application of proposed model is demonstrated on biaxial loading and the results are verified with
testing program using specimens made from S355 steel. Fatigue material parameters for proposed criterion and
multiple sets of data for different combination of axial and torsional loading have been obtained during the
experiment. |
