Viscoelastic properties of nucleus pulposus

Journal of Back and Musculoskeletal Rehabilitation, 1997
Although there have been many studies on the mechanical properties of the annulus fibrosus [1], the fibrous outer layers of the intervertebral disc, there have been fewer studies published on the mechanical properties of its soft centre, the nucleus pulposus [2-4].

Viscoelastic properties of cumulus oöphorus

Biorheology, 1976
An experimental technique suitable for the determination of the rheological properties of minute, biological viscoelastic solid specimens is presented. This technique is employed to ascertain the viscoelastic properties of the rabbit cumulus oöphorus. The experimental results when analyzed using the finite theory of elasticity reveal that the cumulus ...

MR imaging of viscoelastic properties

Journal of Magnetic Resonance Imaging, 1995
AbstractMechanical waves in magnetic resonance imaging, which have been suggested for possible clinical applications, were analyzed with regard to imaging of the viscoelastic properties of large objects. The method is based on the Larmor frequency modulation caused by the application of mechanical waves.

VISCOELASTIC PROPERTIES OF NETWORKS

International Journal of Modern Physics C, 2009
A network was characterized by its viscoelastic properties. The viscoelastic property indicates the deformations or changes in the shape and in the internal structure during the evolution of a network. The change in the direction of motion was taken as elastic deformation and the change in the vertical direction as viscous deformation.

Viscoelastic properties of fibrin clots

Biorheology, 1973
Elastic and viscous properties of fibrin clots were measured in the cone-plate test section of a Weissenberg Rheogonimeter. The tests applied included forced oscillations, free vibrations, and stress relaxation, all in shear. Two classes of clots were studied: (i) ligated clots, formed with the presence of the enzyme fibrinoligase, and (ii) non-ligated

Block Copolypeptides. 2. Viscoelastic Properties

Macromolecules, 1977
The solid state structure of block copolypeptides of gamma-benzyl L-glutamate (G) and L-leucine (L) case from preferential solvents for G has been investigated by dynamic mechanical and wide angle x-ray diffraction techniques. The WAXD patterns show overlapping reflections characteristic of the individual homopolymers.

Viscoelastic Properties of Microtubule Networks

Macromolecules, 2007
Microtubules are filamentous protein biopolymers found in eukaryotic cells. They form networks that guide active intracellular transport and support the overall cell structure. Microtubules are very rigid polymers, with persistence lengths as large as a millimeter.

Attenuation Properties of Viscoelastic Material

pure and applied geophysics, 1989
The attenuation properties of eight Theological models have been studied theoretically. The expressions for Q have been obtained by using dissipated and stored energies and/or complex modulus for each model. The dependence of Q on frequency has been demonstrated.

Combined atomic force microscopy (AFM) and traction force microscopy (TFM) reveals a correlation between viscoelastic material properties and contractile prestress of living cells.

Soft Matter, 2019
Living cells exhibit a complex mechanical behavior, whose underlying mechanisms are still largely unknown. Emerging from the molecular structure and dynamics of the cytoskeleton, the mechanical behavior comprises "passive" viscoelastic material ...
