Journal of Marine Science and Engineering, 2022 This paper investigates the fatigue cyclic deformation behavior of mid-carbon steel. Uniaxial tensile loading tests and fatigue tests under constant and multi-step amplitude loading steps are performed to characterize the influence of loading history ...

Lubricants, 2023 Scaled rolling contact fatigue tests, used to practically simulate the wear of the wheel and rail material under laboratory conditions, are typically classified into two categories. Tests in the first category use twin-disc stands, while the second group

Journal of Marine Science and Engineering, 2022 This work studies the Voce–Chaboche (V–C) material model parameter optimization for high-strength steel welded joints subjected to cyclic loading. The model parameters of each material zone in a S690 steel butt-welded joint were determined using an ...

Analysis of ultimate load-bearing behavior of stiffened plate under axial cyclic loading
Zhongguo Jianchuan Yanjiu, 2022 ObjectivesIn order to improve the accuracy of nonlinear numerical simulation of the ultimate load-bearing behavior of a hull stiffened plate, the effects of ideal elastoplastic, isotropic hardening and cyclic plastic Chaboche material models on the ...

Cyclic plasticity model for fatigue with softening behaviour below macroscopic yielding
Materials & Design, 2019 Experimental observations have evidenced the insufficiency of yield surface definition via monotonic loading to guarantee adequate description of material behaviour under fatigue tests.

Cyclic Attractors Are Critical for Macrophage Differentiation, Heterogeneity, and Plasticity
Frontiers in Molecular Biosciences, 2022 Adaptability, heterogeneity, and plasticity are the hallmarks of macrophages. How these complex properties emerge from the molecular interactions is an open question. Thus, in this study we propose an actualized regulatory network of cytokines, signaling

Circadian gating of neuronal functionality: a basis for iterative metaplasticity
Frontiers in Systems Neuroscience, 2014 Brain plasticity, the ability of the nervous system to encode experience, is a modulatory process leading to long-lasting structural and functional changes.

Cyclic plasticity and fatigue of metals [PDF]
Le Journal de Physique IV, 1993 This report is a survey of the cyclic deformation and fatigue behaviour of selected engineering steels and alloys. Emphasis is placed on the important roles of the cyclic slip mode and the stability of the microstructure during cyclic stressing and on the conditions of fatigue testing with respect to the failure mechanisms and fatigue life.
