Fatigue hardening and fatigue life

Acta Metallurgica, 1972
Abstract Fatigue is explained on the basis of work-hardening using the ideas of the statistical theory of slip. Work-hardening in copper single crystals was studied under prescribed stress as well as strain amplitudes. A conclusion is drawn that cyclic deformation can be divided into two regions: one in which straining is controlled by “cyclic ...

Rolling element fatigue life

Industrial Lubrication and Tribology, 1979
ROLLING‐element bearings for aircraft turbine engine mainshaft applications are generally specified to be made of AISI M‐50 steel. Current aircraft turbine engine manufacturers' material specifications require a double vacuum melted (VIM‐VAR, for vacuum induction melt, vacuum arc smelt) AISI M‐50 steel for mainshaft bearings.

Modelling thermomechanical fatigue life

Materials at High Temperatures, 2002
AbstractIn the present study five different widely used life models were modified to allow for life prediction under thermomechanical fatigue (TMF) loading conditions. In order to assess the predictive capabilities of the models, life prediction results were compared with TMF data obtained on a stainless steel and a SiC particulate reinforced aluminium

Fuzzy fatigue life prediction

Structural Safety, 1989
Abstract Fuzzy set theory is used to encode system uncertainty in a structural reliability analysis. The fatigue failure for joints is described by the common empirical relationship between the applied stress and the corresponding number of stress cycles resulting in a failure.

Life Fatigue: A Critical Analysis

The American Journal of Geriatric Psychiatry
In recent years, euthanasia has been decriminalized or legalized in several countries. The debate on whether to legalize such a practice is open in many places and is a topic that arouses great controversy. Euthanasia has been presented as a response to situations of advanced, incurable, or irreversible disease, or situations that cause intolerable ...

Estimating Fatigue Life

1996
Abstract This article discusses two major approaches in estimating fatigue life from the viewpoint of their use as engineering methods. These include the stress-based (S-N curve) approach and strain-based approach. The stress-based and strain-based approaches are compared, with some comments on their manner of use and limitations.
