Ratcheting-Fatigue Behavior of Harmonic-Structure-Designed SUS316L Stainless Steel
Metals, 2021 Stainless steels with harmonic-structure design have a great balance of high strength and high ductility. Therefore, it is imperative to investigate their fatigue properties for engineering applications.

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 ...

Characterization of the material response in the granular ratcheting [PDF]
, 2005 The existence of a very special ratcheting regime has recently been reported in a granular packing subjected to cyclic loading \cite{alonso04}. In this state, the system accumulates a small permanent deformation after each cycle.

Ratchet behavior in nonlinear Klein-Gordon systems with pointlike inhomogeneities [PDF]
Physical Review E, 2005 We investigate the ratchet dynamics of nonlinear Klein-Gordon kinks in a periodic, asymmetric lattice of point-like inhomogeneities. We explain the underlying rectification mechanism within a collective coordinate framework, which shows that such system behaves as a rocking ratchet for point particles.

Experimental Observation on Viscoplastic Behavior of SUS304. Creep and Ratchetting Behavior.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1993 A unified constitutive model which can predict cyclic plasticity, uniaxial and biaxial ratchetting, creep, and stress relaxation is required by designers of aeronautic equipment, nuclear reactors and so on. Detailed experimental observation of considering viscoplastic behavior of materials must be carried out to construct a unified constitutive model ...
