Thermomechanics of nano-filled elastomers
… of nanoparticles into engineering thermoplastic elastomers affords engineers an opportunity to formulate flexible, tough and multifunctional polymer nanocomposites that potentially rival the most advanced materials in nature. Development of these materials is difficult since thermodynamic and …

Iterative and variational homogenization methods for filled elastomers
… the macroscopic nonlinear elastic behavior of filled elastomers, arguably the most prominent class of elastomeric composites, directly in terms of the behavior of their constituents — i.e., the elastomeric matrix and the filler particles — and their microstructure — i.e., the content, size, …

A study of the mechanical behavior of particle filled elastomers
… properties. In this study, the micromechanics of filled elastomers are studied. We use the simple two dimensional axisymmetric Voronoi - Body Centered Cubic model, created by Socrate and Boyce [4], to aid in predicting the mechanical behavior of filled elastomers by means of a finite element …

Micromechanics of deformation and abrasive wear of fiber-filled elastomers
The abrasive wear of unfilled and fiber-filled elastomers was studied both with experiments and with finite element simulations. Wear experiments with elastomer seals exhibited two distinct regimes: an initial, "break-in" period followed by an "aggressive wear" period. During the break-in period, …

A study of the stretch-induced softening behavior of particle filled elastomers/
Elastomers are able to undergo relatively large deformations in an elastic manner, which makes them the material of choice for a wide range of applications. In some cases, filler particles, such as carbon black, are added to the elastomer to alter the mechanical behavior when subjected to different …

The Effect of Composition on the Linear and Nonlinear Mechanical Properties of Particulate Filled Elastomers
<p>Engineering elastomers are materials capable of undergoing large deformation upon load application and recovering upon load removal. From car tires to building vibration isolator systems, elastomers are the most versatile of engineering materials. The inclusion of particulate fillers into …

Large strain time-dependent behavior of elastomeric materials
… constitutive model for the time-dependence of unfilled elastomers has been developed. The foundation of the model is that the mechanical behavior can be decomposed into two parts: an equilibrium network corresponding to the state that is approached in long time stress relaxation tests; and a …

Polygonal finite elements for finite elasticity
… and convergent. Finally, in the context of filled elastomers and cavitation instabilities, we present applications of practical interest, which utilize polygonal discretizations, demonstrating the potential of polygonal finite elements in studying and modeling nonlinear elastic materials of …

Failure processes in soft and quasi-brittle materials with nonhomogeneous microstructures
… constitutive response of particle reinforced elastomers. When a particle is embedded into an elastomer, the polymer chains in the elastomer tend to adsorb (or anchor) onto the surface of the particle; creating a region in the vicinity of each particle (often referred to as an interphase) with …
