MEAN STRESS EFFECTS IN MULTIAXIAL FATIGUE

Fatigue & Fracture of Engineering Materials & Structures, 1995
Abstract A multiaxial fatigue strain energy density parameter has been formulated which normalizes fatigue data obtained under a variety of mean stress levels and loading combinations. This parameter represents that proportion of the overall strain energy contributed by the stresses and strains on the critical or fracture plane.

Multiaxial Loads and Stresses

2017
Many design tasks are concerned with structural components or systems subject to multicomponent loads. In this case, several forces and moments, which are partially time-independent, can act on the structural component to be evaluated. The local stress state and its variation with time at relevant locations result from the superposition of the local ...

Multiaxial Stress Concentration in Filleted Shafts

Journal of Mechanical Design, 2000
In a previous paper, popular stress concentration factor charts for shoulder filleted shafts in bending and tension were shown to be in error, and more accurate solutions were published. In this paper, improved stress concentration factor information is presented for torsional loading, based on detailed finite element analyses.

Multiaxial Stress-Strain Notch Analysis

2000
Fatigue and durability analyses require the use of analytical and/or numerical methods for calculating elastic-plastic notch tip stresses and strains in bodies subjected to nonproportional loading sequences. The method discussed in the paper is based on the incremental relationships, which relate the elastic and elastic-plastic strain energy densities ...

Fatigue Strength Prediction under Multiaxial Stress

Journal of Composite Materials, 1999
A multiaxial fatigue failure criterion for composite materials is presented in this paper along with an assessment of the capability it offers for design under multiaxial constant or variable amplitude stresses. The applicability of this criterion, based on the well known quadratic failure tensor polynomial criterion for static loading, is validated ...
