A critical review of experimental aspects in ratcheting fatigue: microstructure to specimen to component

Journal of Materials Research and Technology, 2019
In the past three decades ratcheting fatigue has attracted lots of research interest. Ratcheting can be defined as the directional progressive accumulation of plastic deformation of a material when it is subjected to a primary load along with a secondary

Strategic objectives underpin national climate pledges [PDF]

Nature Communications
Emissions-reduction pledges under the Paris Agreement are commonly understood as expressions of domestic preferences. Recent scholarship, however, suggests that governments may also use climate pledges strategically to shape the behavior of other ...

Occurrence of plastic collapse under ratcheting due to gravity and seismic loading

Mechanical Engineering Journal, 2022
The most dominant failure mode of piping components under seismic loading is fatigue failure with ratcheting. While it was confirmed via the experimental tests in the past, the Primary stress limit is applied to seismic loading to prevent plastic ...
