The non-ideal problem behavior using a dynamic vibration absorber with nonlinear essential stiffness and timedependent damping properties
(2013-03-01)
The purpose of this study is to develop a dynamic vibration absorber using viscoelastic material with nonlinear essential stiffness and time-dependent damping properties for a non-ideal vibrating system with Sommerfeld ...
Influence of viscoelastic characteristics of the colloidal suspensions on the formation of SnO2 supported membranes
(1997-12-01)
SnO2 supported membranes have been prepared by sol-casting on alumina tubular substrate, using aqueous colloidal suspensions prepared by sol-gel route. The viscoelastic behaviour during sol ageing was analyzed by dinamic ...
Synthesis of Viscoelastic Behavior Through Electromechanical Coupling
(2020-01-01)
Background: Viscoelasticity is a property of materials that present elastic and viscous behavior when they experience deformation. The simplest model that can represent the viscoelastic behavior is generally called the ...
Impact of calcium on viscoelastic properties of fortified apple tissue
(Wiley, 2011-10)
The objective of this study was to analyze the linear viscoelastic behavior of calcium impregnated apples by creep and sinusoidal tests and to correlate the changes in rheological parameters with some structure features. ...
New developments in isotropic turbulent models for FENE-P fluids
(2018-01-29)
The evolution of viscoelastic turbulent models, in the last years, has been significant due to the direct numeric simulation (DNS) advances, which allowed us to capture in detail the evolution of the viscoelastic effects ...
Effect of freezing on the viscoelastic behavior during the ripening of a commercial low-fat soft cheese
(Elsevier, 2011-05)
The effect of the freezing process (freezing at -25 C, frozen storage at -25 C during 33 days, and thawing at 6 C) on the viscoelastic behavior of a commercial low-fat soft cheese containing microparticulated whey ...
Effect of the solvent viscosity on pure electro-osmotic flow of viscoelastic fluids
(2018-09-01)
In this work the fully-developed steady channel flow of the homogeneous polymer solution studied in [4] is revisited and a completely new analytical solution is proposed which is devoid of the limitations of the previous ...
Experimental analysis of active-passive vibration control using viscoelastic materials and extension and shear piezoelectric actuators
(SAGE PUBLICATIONS LTD, 2011)
Hybrid active-passive damping treatments combine the reliability, low cost and robustness of viscoelastic damping treatments and the high-performance, modal selective and adaptive piezoelectric active control. Numerous ...
Damping behavior of hygrothermally conditioned carbon fiber/epoxy laminates
(2007-12-05)
Carbon fiber reinforced polymer composites have been used in wide variety of applications including, aerospace, marine, sporting equipment as well as in the defense sector due to their outstanding properties at low density. ...
