Mean stress effect remains as a critical aspect in multiaxial fatigue
analysis. This work presents a new criterion which, based on classical
Findley criterion, applies a material-dependent exponent to the mean
normal stress term and includes the ultimate tensile stress as a fitting
parameter. The criterion has been checked against an extended version of
the Papuga database of multiaxial experimental tests with 485 results,
and compared with the criteria by Findley, Robert and Papuga. The new
criterion provides outstanding results for pure uniaxial cases, with
multiaxial performance similar to Robert criterion with a smaller range
of error and a conservative trend. These features enhance the
applicability and versatility of the criterion for its use in fatigue
design of structural components.
