The effect of an occasional mode II loading on the subsequent mode I fatigue crack growth was investigated in a thin-walled 7075-T6511 aluminum alloy tube. Careful observation of crack growth behavior revealed that an occasional mode II loading has t

Experimental results were obtained from fatigue tests of thin-walled 7075-T6 and 2024-T3 aluminium tubular specimens with a circular hole. The loading conditions included axial, torsion, combined in-phase and out-of-phase axial-torsion, and axial wit

Most engineering components and structures contain stress concentrations, such as notches. The state of stress at such concentrations is typically multiaxial due to the notch geometry, and/or multiaxiality of the loading. Significant portions of the

Our formalisation of the Shear Stress-Maximum Variance Method takes as a starting point the hypothesis that, in ductile materials subjected to fatigue loading, the crack initiation planes, i.e. the so-called Stage I planes, are those containing the d

Turbine components are usually designed onto safe-life approach, where the low-cycle fatigue analysis is based on design life curves with suitable probabilistic life margins. However, in order to design for a given reliability, the definition of the

In most fatigue applications, the nominal structural behavior is dominated by elastic deformation, but the fatigue lifetime is significantly influenced by plasticity around stress concentrations and flaws. Although the elastic–plastic behavior can

The analysis of notch stresses and strains is one of the key parts of fatigue life prediction of components and structures, In this paper two related approaches are introduced, covering the whole field from uniaxial to multiaxial non-proportional loa

The mechanism of mixed-mode fatigue crack propagation was investigated in pure aluminum. Push-pull fatigue tests were performed using two types of specimens. One was a round bar specimen having a blind hole, one was a plate specimen having a slit. Th
