The presented analysis demonstrated, for the first time, the applicability of viscoelastic models, previously applied to synthetic polymer materials, to a complex hierarchical biomaterial...

... [ 6,7,13,17–19 ]. The results of this study show that the magnitude and relaxation behavior of the different anatomic regions of the rat brain are significantly different. It also provides region- and age-dependent viscoelastic properties in a form that is compatible with most finite element packages...

... important issues: (1) tissue viscoelasticity; (2) the effects of longitudinal waves and rigid body motion on estimates of shear modulus; and (3) mechanical anisotropy. In the current study we extend the LFE technique to (1) estimate the (complex) viscoelastic shear modulus in lossy media; (2) eliminate...

... deep transverse, midsubstance laceration. Elastic and viscoelastic properties, such as maximum stress, change in stress throughout each test, and stiffness, were measured and compared pre- and post-laceration. Nominal stress and stiffness parameters decreased, albeit disproportionately in magnitude...

... analysis of the fibers alone and with adherent cells. The device is capable of optically recording fiber strain in a cell culture environment. Here we report on the mechanical and viscoelastic properties of highly parallel electrospun poly(ε-caprolactone) fibers. Force-strain data derived from this device...

... )]. Tissue anisotropy has been investigated by stretching strips cut along different directions, i. e., nasal-temporal (NI) and superior-inferior (SI) [( 18 19 )]. Viscoelastic properties have been proved by measuring decreasing forces during relaxation tests, as well as by the measurement of hysteresis...

... in a flexible tube. To evaluate the applicability of the model, we compared theoretical estimations with measured data obtained from basic tube models and a simple arterial model. We constructed different viscoelastic tube set-ups: two straight tubes; one tube connected to two tubes of different elasticity...

To mimic experimental studies performed in fast dynamic compression, a compressive loading velocity of 1 m/s was applied to the superior half of L2, while the inferior half of L3 was fixed. An exploratory technique...

Lieber The material properties of passive skeletal muscle are critical to proper function and are frequently a target for therapeutic and interventional strategies. Investigations into the passive viscoelasticity of muscle have primarily focused on characterizing...

To our knowledge, in ligament and tendon biomechanics, few models describe the unloading behavior qualitatively and quantitatively. The extension of the quasi-linear viscoelastic modeling of Fung ( 9 ) efficiently describes the properties in uniaxial...

The annulus fibrosus is viscoelastic in nature and therefore could express different mechanical responses to applied strain at varying rates. Other viscoelastic tissues, including tendons...
