Fatigue Failure under Varying Loading within Fatigue Limit Diagram

Materials Science Forum, 2007
Although fatigue limit diagram is defined in principle for constant stress amplitude condition, it is often considered that fatigue failure would not occur even in varying loading if applied stresses were kept within the fatigue limit diagram. However, it was shown in the case of small-notched specimen and fretting fatigue that fatigue failure occurred

Mechanical Fatigue Limit for Rubber

Rubber Chemistry and Technology, 1966
Abstract Investigations of the dynamic cut growth behavior of vulcanized rubbers indicate that there is a minimum tearing energy at which mechanical rupture of chains occurs. The limiting value is characteristic of each vulcanizate, but is in the region of 0.05 kg/cm.

Fatigue-Limit Effect on Variable-Amplitude Fatigue of Stiffeners

Journal of the Structural Division, 1979
The effect of the constant-amplitude fatigue limit on the variable-amplitude fatigue life was determined experimentally. Tensile specimens with transverse stiffeners welded either automatically or manually were tested in such a way that, from one set of tests to another, an increasing number of cycles fell below the fatigue limit.

Fatigue damage in polycrystalline copper below the fatigue limit

International Journal of Fatigue, 1994
Abstract Surface fatigue damage was studied in polycrystalline copper cycled with constant plastic strain amplitudes below the fatigue limit. Fatigue damage in this interval of cyclic loading is manifested on the surface of the material as bands of localized cyclic slip: persistent slip bands.

Fretting fatigue under variable loading below fretting fatigue limit

Fatigue & Fracture of Engineering Materials & Structures, 2006
ABSTRACTThe fatigue limit diagram provides the critical condition of non‐failure against fatigue under constant amplitude loading. The fatigue limit diagram is usually considered to give the allowable stress if every stress component is kept within the fatigue limit diagram. In the case of variable amplitude fretting fatigue, however, this study showed

The Limitations of Fatigue Testing

SAE Technical Paper Series, 2010
<div class="section abstract"><div class="htmlview paragraph">Fatigue testing of components is used to validate new product designs as well as changes made to existing designs. On new designs it is common to initially test parts at the design stage (design verification or DV) and then again at the production stage (production verification ...

The fatigue limits of metals

Materials Science and Engineering, 1976
Abstract Recent studies of cyclic deformation in copper single crystals have identified the critical properties of persistent slip bands, known to be the sites of crack nucleation and Stage I propagation in fatigue. From this work, it is concluded that, for almost all metals and alloys, a particular stress and strain will be required to form ...

Fatigue limit of new precipitation-hardened aluminium alloy with distinct fatigue crack propagation limit

International Journal of Fatigue, 2012
Abstract The goal of this study was to confirm the presence of fatigue limit in a plain specimen of a new precipitation-hardened aluminium alloy. The alloy was fabricated by adding 0.53% excess Mg to the standard 6061-T6 aluminium alloy with a balanced Mg 2 Si composition.

Limite de fatigue des métaux

2015
S’il est démontré que la rupture par fatigue peut se produire au-delà de 10^10 cycles, la question de la crédibilité de la notion de limite de fatigue normalisée se pose tant du point de vue pratique que fondamental.Après un état de l'art sur la fatigue gigacyclique des alliages industriels, cet ouvrage compile les résultats les plus récents sur cette ...

Fatigue limits of steels and stress gradient*

Strength of Materials, 2011
Based on generalizing the results of numerous experimental investigations, the empirical relationships between the fatigue limit of steels and the stress gradient are proposed and justified, which take into account the fatigue damage behavior of smooth specimens and specimens with stress concentrators.
