Trabecular bone has been previously recognized as time-dependent (viscoelastic) material, but the relationships of its viscoelastic behaviour with bone volume fraction (BV/TV) have not been investigated so far. Therefore, the aim of the present study was to quantify the time-dependent viscoelastic behaviour of trabecular bone and relate it to BV/TV. Uniaxial compressive creep experiments were p...

An analytical model to predict the linear viscoelastic behavior of thin-walled laminated fiber-reinforced plastic (FRP) composite beams is presented. Using the correspondence principle, this new model integrates micro/macro-mechanics of composites and mechanics of thin-walled laminated beams to perform beam. analyses in the Laplace or Carson domains. The analytical expressions for beam relaxati...

Originating in the field of biomechanics, Fung’s model quasi-linear viscoelasticity (QLV) is one most popular constitutive theories employed to compute time-dependent relationship between stress and deformation soft solids. It simplest models nonlinear viscoelasticity, based on a time-domain integral formulation. In present study, we consider QLV incorporating single scalar relaxation function....

−− Arterial viscoelasticity can be described using stress-relaxation experiments. To fit these curves, models with springs and dashpots, based on differential equations, were widely studied. However, uniaxial tests in arteries show particular shapes with an initial steep decay and a slow asymptotic relaxation. Recently, fractional order derivatives were used to conceive a new component called s...

The effect of oil concentration (from 5 to 47%) and type cellulose ether on the rheological properties (flow linear viscoelasticity), microstructure digestion in o/w emulsions were investigated study. Three types ethers used: a hydroxypropyl methylcellulose (HPMC) two methylcelluloses (MC) with different degrees methoxyl content. All showed shear thinning behaviour. increase emulsion's viscosit...

Ligament viscoelasticity is an important determinant of tissue response to loading, and viscous dissipation modulates the potential for ligament damage or catastrophic failure. The nature of ligament viscoelastic response represents a combined measure of solid phase viscoelasticity and fluid movement. Both of these contributors are likely direction-dependent due to ligament anisotropy. Small si...

Complex coacervation is an associative liquid–liquid phase separation phenomenon resulting from the complexation of oppositely charged macroions. While it well-known that behavior and rheological character coacervates can vary as a function identity various species present (i.e., macroions, salt, solution conditions), effect solvent quality has been rarely studied. Here, adding small amounts ei...
