TLDR
In this article, load relaxation studies were carried out to test for the existence of a plastic equation of state in high purity polycrystalline aluminium, and the tests verified that such an equation was stable against static recovery up to at least 0.45 T m.About:

Kinetics of flow and strain-hardening☆
H. Mecking,U.F. Kocks +1 more
TL;DR: In this paper, a phenomenological model is proposed to incorporate the rate of dynamic recovery into the flow kinetics, which has been successful in matching many experimental data quantitatively, and it has been shown that the proportionality between the flow stress and the square root of the dislocation density holds, to a good approximation, over the entire regime; mild deviations arc primarily attributed to differences between the various experimental techniques used.

Prediction of nonlinear viscoelastic behavior of polymeric composites using an artificial neural network
TL;DR: In this paper, a nonlinear viscoelastic constitutive model is developed, and its material parameters are determined by fitting it to creep test data, and an alternative model based on an artificial neural network (ANN) is developed to predict the stress relaxation of the polymer matrix composite.

Seismic wave attenuation: Energy dissipation in viscoelastic crystalline solids
TL;DR: In this paper, the mineral physics/materials science of mechanical absorption, specifically in dense materials at elevated temperature, is discussed, and the interest is in employing the physical study of mechanics to understand natural phenomena such as those mentioned above.

XLI. The equilibrium of linear arrays of dislocations.
TL;DR: In this article, a method for finding the equilibrium positions of a set of like dislocations in a common slip-plane under the influence of a given applied stress is given by the roots of a certain set of orthogonal polynomials.

Steady‐State Creep through Dislocation Climb
TL;DR: In this article, a dislocation climb creep model is considered which does not require the production of immobile dislocations, and the creep equation that results from the analysis is creep rate = Aσ3sinh(Bσ1.5/kT)exp(−Q/kTs), where A and B are constants, σ is the stress, Q is the activation energy of creep and kT has its usual meaning.

A phenomenological theory for plastic deformation of polycrystalline metals
TL;DR: In this paper, a phenomenological theory for the plastic deformation properties of a restricted class of polycrystalline metals is developed, and conditions that must be satisfied if a plastic equation of state is to hold are investigated.
