Ratcheting behavior of Eurofer97 at 550 °C
Nuclear Materials and Energy, 2018 The components in reactor are usually exposed to cyclic loading caused by frequent startups, shutdown and load fluctuations which lead to ratcheting effect.

CRYOGENIC RATCHETING OF PRESTRAINED AUSTENITIC STAINLESS STEEL S30408
Jixie qiangdu, 2020 Taking advantage of the EUM-25 K20 tension-torsion fatigue testing machine by CARE,the cryogenic uniaxial ratcheting tests were carried out for the S30408 specimens with and without weld,and with 0%,8%,and 12% pre-strains at110 K.

Numerical simulation of ratcheting and fatigue behaviour of mitred pipe bends under in-plane bending and internal pressure [PDF]
, 2013 This paper investigates the ratcheting and fatigue behaviour of 90 degree single unreinforced mitred pipe bends subjected to a cyclic in-plane closing moment with a non-zero mean value and constant internal pressure. An experiment was conducted to induce

A Temperature-Dependent Model of Shape Memory Alloys Considering Tensile-Compressive Asymmetry and the Ratcheting Effect. [PDF]
Materials (Basel), 2020 Tensile-compressive asymmetry and the ratcheting effect are two significant characteristics of shape memory alloys (SMAs) during uniaxial cyclic tests, thus having received substantial attention in research.

Ratchet analysis of structures under a generalised cyclic load history [PDF]
, 2014 This paper introduces a new approach based upon the Linear Matching Method in order to obtain the ratchet limit of structures subjected to an arbitrary thermo-mechanical load history. This method varies from the traditional Linear Matching Method ratchet

Investigating asymmetric ratcheting effect on budgeted earnings in Tehran Stock Exchange [PDF]
بررسیهای حسابداری و حسابرسی, 2015 Asymmetric ratcheting effect occurs when an unfavorable (favorable) budget variance causes in increase (decrease) in next period’s budget. The current study aims to investigate the existence of this effect on budgeted earning in Tehran stock exchange. We

Optimal Ratcheting of Dividends in a Brownian Risk Model [PDF]
, 2020 We study the problem of optimal dividend payout from a surplus process governed by Brownian motion with drift under the additional constraint of ratcheting, i.e. the dividend rate can never decrease.
