Behavior of viscoelastic models with thermal fluctuations

Mode Ii Fracture Behavior of Bonded Viscoelastic Thermal Compressed Wood

The influence of viscoelastic thermal compression (VTC) of wood on bonding performance was studied. Mode-II (shear mode) fracture of the bonded interphase was performed using the overnotched and end-notched flexure methods. The study examined four groups of specimens; a control and VTC specimens with three different degrees of densification (63, 98, and 132%). The specimens were bonded with phe...

Application of nonlinear viscoelastic models to describe ligament behavior.

Recent experiments in rat medial collateral ligament revealed that the rate of stress relaxation is strain dependent and the rate of creep is stress dependent. This nonlinear behavior requires a more general description than the separable quasilinear viscoelasticity theory commonly used in tissue biomechanics. The purpose of this study was to determine whether the nonlinear theory of Schapery o...

Role of fluctuations in membrane models: thermal versus nonthermal.

We study the comparative importance of thermal to nonthermal fluctuations for membrane-based models in the linear regime. Our results, both in 1+1 and 2+1 dimensions, suggest that nonthermal fluctuations dominate thermal ones only when the relaxation time τ is large. For moderate to small values of τ, the dynamics is defined by a competition between these two forces. The results are expected to...

Viscoelastic Modeling of the Recovery Behavior of Cut Pile Carpet After Static Loading: A Comparison Between Linearand Nonlinear Models

Thermal Conductivity and Viscoelastic Properties of UV-curable Urethane Acrylate Reinforced with Modified Al2O3 Nanoparticles

In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...
