Time dependent behaviour of fluids filled geomaterials: application to reservoir formations [PDF]

open access: yes, 2009
International audienceIn this paper a rate dependent model for geomaterials saturated by a mixture of immiscible fluids is presented. The proposed constitutive law generalizes the isotach approach to the elastoplastic strain hardening based constitutive ...

Analyzing the characteristics of the cavity nucleation, growth and coalescence mechanism of 9Cr-1Mo-VNb steel (P91) steel [PDF]

open access: yes, 2013
Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to assist safe operation.

A new shear rheological model for a soft interlayer with varying water content

open access: yesWater Science and Engineering, 2018
The rheological behavior of a soft interlayer is critical to understanding slope stability, which is closely related to the water content of the soft interlayer. This study used the soft interlayer of the Permian Maokou Formation in Southwest China as an

A unified creep-plasticity model suitable for thermo-mechanical loading [PDF]

open access: yes
An experimentally based unified creep-plasticity constitutive model was implemented for 1070 steel. Accurate rate and temperature effects were obtained for isothermal and thermo-mechanical loading by incorporating deformation mechanisms into the ...

Creep and creep rupture of laminated graphite/epoxy composites [PDF]

open access: yes
An incremental numerical procedure based on lamination theory is developed to predict creep and creep rupture of general laminates. Existing unidirectional creep compliance and delayed failure data is used to develop analytical models for lamina response.

The behavior of structures based on the characteristic strain model of creep [PDF]

open access: yes, 2011
There has been much work over the past two decades to aid the design and assessment engineer in the selection of a suitable material model of creep for high temperature applications.

CREEP DAMAGE CONSTITUTIVE MODEL OF FE-CR-NI BASED AUSTENITIC STAINLESS STEEL

open access: yesJixie qiangdu, 2022
Considering the effect of carbide coarsening and void nucleation and growth on the creep damage of Fe-Cr-Ni based austenitic stainless steel, a new creep damage constitutive model was established based on the hyperbolic sinh function, and material ...

Creep Mechanics of the High-Stress Soft Rock under Grade Unloading

open access: yesAdvances in Civil Engineering, 2020
In order to study the creep behavior of deep soft rock, gritstone was chosen as the research subject, and a rock triaxial rheometer (Rock 600-50) and acoustic emission (AE) system (SH-II) were used to carry out the grade unloading confining pressure ...
