Nonlinear Creep Constitutive Model of Rock Considering Hardening Effect

open access: yesGeofluids
The creep of rock is a complex mechanical phenomenon driven by internal stress adjustment and the interplay between hardening and damage effects. To precisely capture the nonlinearity of rock creep and the law of accelerated deformation, a hardening ...

A new swelling - creep model for red-bed mudstone and its application

open access: yesFrontiers in Earth Science
In the red-bed region, engineering structures often encounter safety risks due to the swelling and creep properties of mudstone. Presently, there is a deficiency in constitutive equations capable of characterizing mudstone behavior under combined stress ...

Effects of state recovery on creep buckling under variable loading [PDF]

open access: yes
Structural alloys embody internal mechanisms that allow recovery of state with varying stress and elevated temperature, i.e., they can return to a softer state following periods of hardening.

Constitutive Equations for Use in Design Analyses of Long-life Elevated Temperature Components [PDF]

open access: yes, 1983
Design analysis needs and procedures relative to elevated temperature components in liquid metal fast breeder reactor (LMFBR) system were examined. The effects of the thermal transients on the pressure boundary components are enhanced by the excellent ...

Visco-elastoplastic constitutive model for remolded loess based on infinitesimalization of plastic elements

open access: yesYantu gongcheng xuebao
Based on the theory of infinitesimalization of plastic elements and infinite series, the visco-elastoplastic constitutive model for remolded loess is established through the triaxial creep tests under loading and unloading conditions and verified by the ...

Matrix dominated stress/strain behavior in polymeric composites: Effects of hold time, nonlinearity and rate dependency [PDF]

open access: yes
In order to understand matrix dominated behavior in laminated polymer matrix composites, an elastic/viscoplastic constitutive model was developed and used to predict stress strain behavior of off-axis and angle-ply symmetric laminates under in-plane ...

Rheological Model for Wood [PDF]

open access: yes, 2014
Wood as the most important natural and renewable building material plays an important role in the construction sector. Nevertheless, its hygroscopic character basically affects all related mechanical properties leading to degradation of material ...
