The nature of elastomeric material demands the consideration of finite deformations, nonlinear elasticity including damage as well as rate-dependent and rate-independent dissipative properties. While many models accounting for these effects have been refined over time to do better justice to the real behavior of rubber-like materials, the realistic simulation of the elastoplastic characteristics for filled rubber remains challenging.

Irreversible thermodynamics of triple junctions during the intergranular void motion under the electromigration forces
Ogurtani, TO; Oren, EE (Elsevier BV, 2005-06-01)
A rigorous reformulation of internal entropy production and the rate of entropy flow is developed for multi-component systems consisting of heterophases, interfaces and/or surfaces. The result is a well-posed moving boundary value problem describing the dynamics of curved interfaces and surfaces associated with voids and/or cracks that are intersected by grain boundaries. Extensive computer simulations are performed for void configuration evolution during intergranular motion. In particular we simulate evol...
Coupled thermoviscoplasticity of glassy polymers in the logarithmic strain space based on the free volume theory
Miehe, Christian; Mendez Diez, Joel; Göktepe, Serdar; Schaenzel, Lisa Marie (Elsevier BV, 2011-06-15)
The paper outlines a constitutive model for finite thermo-visco-plastic behavior of amorphous glassy polymers and considers details of its numerical implementation. In contrast to existing kinematical approaches to finite plasticity of glassy polymers, the formulation applies a plastic metric theory based on an additive split of Lagrangian Hencky-type strains into elastic and plastic parts. The analogy between the proposed formulation in the logarithmic strain space and the geometrically linear theory of pl...
On principal shear axes for correction factors in Timoshenko beam theory
Dong, S. B.; Carbas, S.; Taciroglu, E. (Elsevier BV, 2013-05-15)
Compelling arguments with substantiating data are presented to explain why there is no role for principal shear axes in shear correction factors of Timoshenko beam theory. This article supplies more details to the explanation in a previous paper on this issue.
A variational approach for the two-dimensional magnetopolaron
Erçelebi, Atila; Saqqa, Bassam H. (IOP Publishing, 1989-12-18)
The problem of a two-dimensional magnetopolaron is investigated on the basis of a variational theory consisting of an adiabatic polaronic wavefunction combined with a perturbative correction by which it is possible to interrelate the strong and weak coupling counterparts of the coupled electron-phonon system. It is seen that the theory conveniently reproduces the desirable asymptotic limits in the different regimes of the problem. Furthermore, it is suggested that a satisfying improvement should be achieved...
A new formulation for the analysis of elastic layers bonded to rigid surfaces
Pinarbasi, Seval; Akyüz, Uğurhan; Mengi, Yalcin (Elsevier BV, 2006-07-01)
Elastic layers bonded to rigid surfaces have widely been used in many engineering applications. It is commonly accepted that while the bonded surfaces slightly influence the shear behavior of the layer, they can cause drastic changes on its compressive and bending behavior. Most of the earlier studies on this subject have been based on assumed displacement fields with assumed stress distributions, which usually lead to "average" solutions. These assumptions have somehow hindered the comprehensive study of s...
