On cyclic yield strength in definition of limits for characterisation of fatigue and creep behaviour

open access: yesOpen Engineering, 2017
This study proposes cyclic yield strength as a potential characteristic of safe design for structures operating under fatigue and creep conditions.

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]

open access: yes, 2017
The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

Cyclic plasticity model for fatigue with softening behaviour below macroscopic yielding

open access: yesMaterials & 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

open access: yesFrontiers 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

Structural integrity assessment of superheater outlet penetration tubeplate [PDF]

open access: yes, 2009
In recent years, the Linear Matching Method (LMM) has been well developed for the integrity assessment of the component subjected to cyclic thermal and mechanical loads.

Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718

open access: yes, 2018
A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys.

Circadian gating of neuronal functionality: a basis for iterative metaplasticity

open access: yesFrontiers 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.

A simplified creep-reverse plasticity solution method for bodies subjected to cyclic loading [PDF]

open access: yes, 2004
An extension of the upper bound shakedown theorem to load histories in excess of shakedown has been applied recently to the evaluation of a ratchet limit and the varying plastic strain magnitudes associated with a varying residual stress field. Solutions

Evaluation of Three Constitutive Models for the Prediction of Hastelloy X Elevated Temperature Cyclic Response [PDF]

open access: yes, 1983
The approach for the method development assumes that, for a thermally loaded structure, the overall strain history is defined by linear elastic analysis.

Shakedown and limit analysis of 90° pipe bends under internal pressure, cyclic in-plane bending and cyclic thermal loading [PDF]

open access: yes, 2011
The Linear Matching Method is used to create the shakedown limit and limit load interaction curves of 90 degree pipe bends for a range of bend factors.
