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.

Local Ratcheting Phenomena in the Cyclic Behavior of Polycrystalline Tantalum [PDF]
JOM, 2019 A direct numerical simulation of the cyclic response of a 250-grain polycrystalline aggregate over more than 1000 cycles is presented, being one of the few available simulations including a significant number of cycles. It provides unique results on the evolution of the accumulated plastic strain and ratcheting phenomena inside the grains.

Characterization and Modeling of the Ratcheting Behavior of the Ferritic-Martensitic Steel P91
, 2015 In this work, the ratcheting-behavior of 9%Cr-1%Mo ferritic–martensitic steel is studied with uniaxial cyclic loading. To describe the ratcheting-behavior of this steel, a visco-plastic constitutive model with consideration of cyclic softening of Reduced Activation Ferritic Martensitic steels is further modified, based on the analysis of back stress.

Harmonic ratcheting for fast acceleration
Physical Review Special Topics. Accelerators and Beams, 2014 A major challenge in the design of rf cavities for the acceleration of medium-energy charged ions is the need to rapidly sweep the radio frequency over a large range.

Non-Stationary Effect on the Behavior of an On-Off Ratchet [PDF]
Progress of Theoretical Physics, 2006 The behavior of an on-off ratchet driven by a non-stationary effect is examined numerically. We find that at the stationary/non-stationary transition, mean velocity of the on-off ratchet is independent of mean residence time, in contrast to the situation for a conventional on-off ratchet, whose mean velocity is quite sensitive to the mean residence ...
