Mechanical Behavior of Coupled Elastoplastic Damage of Clastic Sandstone of Different Burial Depths

open access: yesEnergies, 2020
Clastic sandstone is widely distributed in oil and gas reservoirs; its internal structure has many micro-defects. Under different stress environments of burial depth, significant damage evolution and plastic deformation easily occur. A series of triaxial

Behavior of Elastoplastic Auxetic Microstructural Arrays [PDF]

open access: yesMaterials, 2013
A continuum-based micromechanical model is employed for the prediction of the elasto-plastic behavior of periodic microstructural arrays that can generate negative values of Poisson’s ratios. The combined effects of the negative Poisson’s ratio generated by the array microstructure and the elastoplastic behavior of the constituents are studied.

Relative Entropy Application to Study the Elastoplastic Behavior of S235JR Structural Steel. [PDF]

open access: yesMaterials (Basel), 2023
The main issue in this work is to study the limit functions necessary for the reliability assessment of structural steel with the use of the relative entropy apparatus. This will be done using a few different mathematical theories relevant to this relative entropy, namely those proposed by Bhattacharyya, Kullback–Leibler, Jeffreys, and Hellinger ...

Elastoplastic behavior of yield stress fluids [PDF]

open access: yesPhysical Review Fluids, 2019
By means of the incremental elastic modulus for small deformations superimposed on creep and subsequent recovery tests, we follow the structural state of various soft-jammed systems (yield stress fluids) in their solid regime. We demonstrate that the solid state of the material is associated with a persistent elastic network of constant elastic modulus

On short cracks that depart from elastoplastic notch tips [PDF]

open access: yesFracture and Structural Integrity, 2017
The behavior of short cracks that depart from elastoplastic notch tips is modeled to estimate the stresses required to initiate and to propagate cracks in notched structural components, and to evaluate the size of tolerable crack-like defects under ...

A constitutive model for hydromechanically coupled behavior of unsaturated soils with hydraulic hysteresis [PDF]

open access: yesMATEC Web of Conferences, 2021
There are several constitutive models developed for understanding coupled hydromechanical behavior of three phase medium of unsaturated soils as well as models for explaining hydraulic hysteresis in water retention.

Numerical study of TRIP transformation in 35NCD16 steel-effects of plate orientation and some criteria

open access: yesFracture and Structural Integrity, 2022
This study aims to analyze the effect of thermo mechanical coupling damage in the presence of a phase change (austenite/martensite) in 35NCD16 steel. The impact of increasing mechanical traction load, accompanied by a martensitic transformation on the ...
