Effects of thermal aging on uniaxial ratcheting behavior of vulcanised natural rubber

Polymer testing, 2018
Vulcanised natural rubber (NR) tends to be hardened and lose damping capability as it is used at high temperature for a long period of time. Therefore, the thermal aging effects on the cyclic response of vulcanised NR need to be considered.

Ratcheting Behavior of a Titanium-Stabilized Interstitial Free Steel

Metallurgical and Materials Transactions A, 2012
Engineering stress-control ratcheting behavior of a titanium-stabilized interstitial free steel has been studied under different combinations of mean stress and stress amplitude at a stress rate of 250 MPa s−1. Tests have been done up to 29.80 pct true ratcheting strain evolution in the specimens at three maximum stress levels. It is observed that this

Microstructure and ratcheting behavior of 6061 aluminum alloy laser-MIG hybrid welding joint

Materials Research Express, 2019
In this paper, 6061-T6 aluminum alloy was welded by laser-MIG hybrid welding. The microstructures of the upper part of the weld center, the lower part and the edge of the weld near the fusion line in the welded joint were analyzed.

Tensile ratcheting behaviors of bronze powder filled polytetrafluoroethylene

Frontiers of Chemical Science and Engineering, 2013
A series of tensile and ratcheting experiments for compacted polytetrafluoroethylene (PTFE) and bronze filled PTFE (PTFE/bronze) were conducted on dynamic mechanical analyzer (DMA-Q800). The effects of mean stress, stress amplitude and temperature on the ratcheting behaviors of PTFE and PTFE/bronze were investigated.

Micromechanical Modeling of the Ratcheting Behavior of 304 Stainless Steel

Journal of Engineering Materials and Technology, 2016
Numerical simulations of 304 austenitic stainless steel (SS304) cyclic and ratcheting responses are performed using polycrystalline plasticity models. On the basis of the polycrystalline model of Cailletaud and Pilvin (1994, “Utilisation de modèles polycristallins pour le calcul par éléments finis,” Rev. Eur. Élém. Finis, 3, pp.

Ratchetting behavior of 20MnMoNi55 reactor pressure vessel steel

Journal of Nuclear Materials, 2015
Abstract Uniaxial ratchetting characteristics of 20MnMoNi55 steel at room temperature were studied experimentally. The effects of stress amplitude and mean stress on the ratchetting behavior of the steel were analyzed. It can be concluded that the ratchetting strain amplitude and ratchetting strain rate of 20MnMoNi55 steel increases with increasing ...
