A Potential Function Derivation of a Constitutive Equation for Inelastic Material Response [PDF]

open access: yes, 1983
Physical and thermodynamic concepts are used to develop a potential function for application to high temperature polycrystalline material response. Inherent in the formulation is a differential relationship between the potential function and constitutive

FE implementation of damage-coupled inelastic constitutive equation for P91 steel

open access: yesMechanical Engineering Journal
The objective of this study is to numerically evaluate the cyclic softening behavior and creep-fatigue damage of P91 steel. To achieve this, a damage-coupled inelastic constitutive equation is formulated by coupling the Chaboche-type viscoplastic ...

On the time-dependent behaviour of unsaturated geomaterials [PDF]

open access: yes, 2010
International audienceIn this paper a rate dependent model for unsaturated geomaterials is presented. The constitutive laws for the description of the time-dependent behaviour of saturated and partially saturated geomaterials generalize the isotach ...

Forced oscillations of a body attached to a viscoelastic rod of fractional derivative type

open access: yes, 2012
We study forced oscillations of a rod with a body attached to its free end so that the motion of a system is described by two sets of equations, one of integer and the other of the fractional order.

Micromechanically Based Constitutive Relations for Polycrystalline Solids [PDF]

open access: yes, 1983
A basic method to estimate the overall mechanical response of solids which contain periodically distributed defects is presented. The method estimates the shape and growth pattern of voids periodically distributed over the grain boundaries in a viscous ...

Creep constitutive model of 7050⁃T7451 aluminum alloy based on damage mechanics

open access: yesJixie qiangdu
The creep behavior of 7050-T7451 aluminum alloy under different temperatures and stresses was studied by the uniaxial tensile creep test. Based on continuum damage mechanics, a constitutive model describing the creep behavior of aluminum alloy at high ...
