TL;DR: In this paper, cyclic strain-controlled fatigue properties of low-alloy multiphase transformation-induced plasticity steel (TRIP steel) and dual-phase steel (DP steel) were investigated experimentally.

TL;DR: In this paper, a simple method for estimating the local strain at the notch root was proposed in tension and torsion loading in multiaxial low cycle fatigue was discussed in two materials.

TL;DR: In this paper, a non-circular hole shape was used to increase the initial fatigue life for all specimens used, where the nominal area was allowed to vary nominal area using design variables resulting in decreasing the nominal stress in addition to decreasing the stress concentration factor.

TL;DR: In this paper, the authors developed an approach with two driving force parameters to analyze the fatigue behavior and found that the internal stress is the missing link that can bridge the gap between the four main stages of damage.

TL;DR: In this paper, a unified analysis to both high and low cycle fatigue based on elastic shakedown theories and dissipated energy is presented, with a presentation of the fatigue phenomena at different scales (microscopic, mesoscopic and macroscopic).
Abstract: The purpose of this paper is to present a unified analysis to both high and low cycle fatigue based on shakedown theories and dissipated energy. The discussion starts with a presentation of the fatigue phenomena at different scales (microscopic, mesoscopic and macroscopic) and of the main shakedown theorems. A review of the Dang Van high cycle fatigue criterion shows that this criterion is essentially based on the hypothesis of elastic shakedown and can therefore be expressed as a bounded cumulated dissipated energy. In the low cycle fatigue regime, recent results by Skelton and Charkaluk et al. show that we can speak of a plastic shakedown at both mesoscopic and macroscopic scale and of a cumulated energy bounded by the failure energy. The ideas are also justified by infrared thermography tests permitting a direct determination of the fatigue limit.

TL;DR: In this paper, the influence of multiaxial stress/strain states on the fatigue behavior of a compoment under elasto-plastic deformations can be determined reliably with unnotched specimens only by deformation controlled tests, if plastic racheting is not expected in critical areas.
