<p style='text-indent:20px;'>The purpose of this paper is to investigate the stabilization a locally coupled wave equations with non smooth localized viscoelastic damping Kelvin-Voigt type and time delay. Using general criteria Arendt-Batty, we show strong stability our system in absence compactness resolvent. Finally, using frequency domain approach combined multiplier method, prove poly...

A thermodynamically consistent model for soft deformable viscoelastic magnets is formulated in actual space (Eulerian) coordinates. The possibility of a ferro-paramagnetic-type (or ferri-antiferromagnetic) transition exploiting the Landau phase-transition theory as well mechanical melting or solidification considered, being motivated and applicable to paleomagnetism (involving both thermo- isot...

The performance and construction of a new algorithm for the calculation of infrared cooling rates and fluxes in terrestrial general circulation models are described in detail. The computational method, which is suitable for use in models of both the troposphere and the middle atmosphere, incorporates effects now known to be important, such as an extended water vapor e-type continuum, careful tr...

The generalized dynamical theory of thermo-elasticity proposed by Green and Lindsay is applied to study the propagation of harmonically time-dependent thermo-viscoelastic plane waves of assigned frequency in an infinite visco-elastic solid of Kelvin-Voigt type, when the entire medium rotates with a uniform angular velocity. A more general dispersion equation is deduced to determine the effects ...

The dynamic response of an initially flat viscoelastic membrane is investigated. The viscoelastic model is described with fractional order derivatives. The membrane is subjected to surface transverse and inplane dynamic loads. The governing equations are three coupled second order nonlinear partial FDEs (fractional differential equations) of hyperbolic type in terms of the displacement componen...

During the last few decades, the use of flexible structural systems has steadily increased importance. The study of a flexible aerospace structure is a problem of dynamical system theory governed by partial differential equations. We consider here the problem of characterize well posedness, for a mathematical model of a flexible space structure like a thin uniform rectangular panel. For example...

In this paper initial boundary value problems, defined using quasilinear diffusion equations of Volterra type, are considered. These equations arise for instance to describe diffusion processes in viscoelastic media whose behaviour is represented by a Voigt-Kelvin model or a Maxwell model. We propose a finite difference discretization defined on a general nonuniform grid and we show second conv...

This paper presents the implementation of a planetary rover simulation environment focused on locomotion aspects. A multibody, port-based modeling approach was taken combined with screw theory for the description of the kinematics and dynamics. Bond graphs are used as the modeling language. The contact model considers the interacting surfaces to be smooth and utilizes their differential geometr...
