Creep constitutive model of strain energy density considering the whole process of creep deformation.

PLoS ONE
Aiming at the problem that the traditional creep model is difficult to reflect the characteristics of accelerated creep stage of rock, the influence of stress state on accelerated creep is fully considered, and a constitutive model which can describe ...

Study on Creep Behavior of Wenzhou Remolded Coastal Silt Under One-Dimensional and Triaxial Tests

Buildings
This study investigates the creep behavior of remolded Wenzhou (China) coastal silt through one-dimensional (1D) and triaxial creep tests. Results show that the secondary consolidation coefficient exhibits a non-monotonic response to stress levels, while

Testing the shearing creep of composite geomembranes-cushion interface and its empirical model

Soils and Foundations, 2022
An accurate description of composite geomembranes (CGs)–cushion interface behaviour (particularly creep behaviour) is of great importance. This paper presents a creep experiment method for studying the shearing creep characteristics of CGs–cushion ...

Creep characteristics and constitutive model construction of offshore soft soils

Journal of Traffic and Transportation Engineering (English ed. Online)
The main objective of this study was to investigate creep characteristics and construct a suitable constitutive model for soft soils in offshore areas. Soft soil samples were obtained to evaluate the physical and mechanical properties.

Experimental investigation of the mechanical properties of mud shale under water-bearing conditions and its applications

Scientific Reports, 2022
Mud shale, used in drilling engineering, is prone to hydration and expansion, resulting in creep deformation that leads to wellbore shrinkage and pipe sticking incidents.

Harmonics of the AC susceptibility as probes to differentiate the various creep models

, 2003
We measured the temperature dependence of the 1st and the 3rd harmonics of the AC magnetic susceptibility on some type II superconducting samples at different AC field amplitudes, hAC.

Viscoelastic-plastic damage creep model for rock

Yantu gongcheng xuebao, 2020
Based on the classical element model, the nonlinear element and the creep damage are introduced to solve the problem that the classical element model cannot describe the non-linear characteristics of rock during the whole compressive creep process ...

Creep damage constitutive model of rock based on the mechanisms of crack-initiated damage and extended damage

Underground Space
Since the classical element model cannot describe the nonlinear characteristics of rock during the entire compressive creep process, nonlinear elements and creep damage are generally introduced in the model to resolve this issue.

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

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