Soft tissues exhibit a nonlinear, essentially incompressible (visco-) elastic response; a key issue is the active nature of muscle fibres, in other words their ability to contract and relax in response to biochemical signals. Here we present a continuum model able to describe an active elastic medium.

It has been known for over a century that the lungs retain some of their elastic properties after death. Carson (1820) was the first to investigate the elastic recoil of the lungs by measuring the force required to inflate them, and this type of experiment has been repeated by numerous investigators with confusing results. The only conclusion that can be drawn from the literature is that the el...

Motywacją do badań nad równaniami opisującymi odkształcenia termo-lepko-sprężyste jest potrzeba lepszego opisu procesów zachodzących w różnych materiałach oraz zbudowania lepszych modeli ich zachowania pod wpływem działania sił zewnętrznych. Wraz z rozwojem techniki zdobywamy głębszą wiedzę na temat różnych tworzyw. Pozwala nam to na tworzenie coraz bardziej poprawnych modeli opisujących zachow...

| In this paper, we describe models and algorithms designed to produce eecient and physically consistent dynamic simulations. These models and algorithms have been implemented in a unique framework, modeling both deformations and contacts through visco-elastic relations. Since this model of interaction (known as \penalty based") is much debated, we present it in detail. Indeed, the \penalty" ba...

An analysis of radiation and soret effect on visco-elastic mhd oscillatory flow with heat and mass transfer through a porous medium bounded by two infinite horizontal parallel porous plates in presence of chemical reaction and a heat source has been presented when one plate is kept at rest while the other is oscillating in its own plane. The fluid is considered to be non-Newtonian characterized...

This research presents, buckling and free vibration analysis of fiber metal-laminated (FML) plates on a total and partial elastic foundation using the generalized differential quadrature method (GDQM). The partial foundation consists of multi-section Winkler and Pasternak type elastic foundation. Taking into consideration the first-order shear deformation theory (FSDT), FML plate is modeled and...

It is well known that the Poiseuille flow of a visco-elastic polymer fluid between plates or through a tube is linearly stable in the zero Reynolds number limit, although the stability is weak for large Weissenberg numbers (Wi). In this paper, we argue that recent experimental and theoretical work on the instability of visco-elastic fluids in Taylor–Couette cells and numerical work on channel f...

An analysis of free convective MHD visco-elastic fluid flow with heat and mass transfer over a vertical plate moving with a constant velocity in presence of Dufour and Soret effects has been presented. The fluid is considered to be non-Newtonian characterized by Walters liquid (Model B′). The surface temperature is assumed to oscillate with small amplitude about a non-uniform mean temperature. ...

We consider a general mathematical model which describes the quasistatic contact of deformable body with an obstacle, so-called foundation. The material’s behaviour is modeled visco-elastic-type constitutive law and described interface associated to version Coulomb’s dry friction. list assumptions on data provide relevant examples laws boundary conditions. Then, we derive two different variatio...
