| description | This study aims to investigate fatigue damage resulting from multiaxial fatigue, proportional and/or
nonproportional, loading by analyzing stresses and strains over a full domain around a representative stress-strain
element. Plain stress-strain transformation of multiaxial hysteresis was performed by varying orientation of plane
for 0≤φ≤2π. Parametric representations for both normal and shear stresses and strains were obtained by plotting
them in polar figures. These figures show that depending on the applied loading stresses and strains represent
definitive known parametric curves.
Parametric representation of fatigue damage parameter such as Fatemi-Socie suggests that fatigue damage shall
be calculated as the sum of the damage values on all planes. The proposed technique has been shown to improve
fatigue life prediction compared to that obtained from the critical plane method. |
