Elastic excitable medium

Physical Review E, 1994
A type of excitable medium---an elastic excitable medium---has been created by incorporating the Belousov-Zhabotinsky reaction into a polyacrylamide-silica gel. It permits one to address the problem of how the cardiac muscle contractions affect the dynamics of rotating spiral waves.

Stiffness Coefficients of Elastic Medium

Journal of the Geotechnical Engineering Division, 1982
Using the theory of elasticity, values of stiffness coefficients for vertical and horizontal modes are evaluated for cases for which solutions are not available. Three types of pressure distributions and three types of displacement conditions are considered.

Fourdimensional elastic medium

Acta Mechanica, 1974
A theory of the fourdimensional elastic medium, similar to the theory of the threedimensional one, is developed. As an illustration, the wave velocities of the dilatational and rotational waves in the Minkowski space of special relativity are determined.

Dynamical Behaviour of Orthotropic Micropolar Elastic Medium

Journal of Vibration and Control, 2002
The present paper is concerned with the plane strain problem in homogeneous micropolar orthotropic elastic solids. The disturbance due to continuous normal and tangential sources are investigated by employing eigenvalue approach. The integral transforms have been inverted by using a numerical technique to obtain the normal displacement, normal force ...

Elastic medium containing interacting fluid inclusions

Composite Structures, 2021
Abstract We extend the Eshelby’s (equivalent) inclusion method to consider ellipsoidal volumes occupied by fluids of limited compressibility. The new method decomposes the problem into two parts – a stress free transformation problem, and a volume compatibility problem.

FREE VIBRATION OF ELASTIC MEDIUM

ISET Journal of Earthquake Technology, 1975
The dynamics of elastic m~dia has been studied in the past mainly from the wave propagation point of view (Ewing et ai, 1957). This is probably because of the importance of such problems in fields like geophysics, wherein one mostly considers layers of infinite length or layers of infinite depth.

Solitons in a Nonlinear Elastic Medium

Materials Science Forum, 1991
The influence of nonlinearity on shear horizontal elastic (bulk and surface) waves in crystals is considered on the basis of a nonlinear equation derived from a microscopic scalar model. The continuum limit is compared with the equation obtained in the framework of nonlinear elasticity theory.

Point Defect in a Nonlocal Elastic Medium

Journal of Mathematical Sciences, 2001
A nonlinear elastic body is studied in the framework of the model proposed by \textit{A.C.~Eringen} [Int. J. Engin. Sci. 10, No.~5, 425--435 (1972; Zbl 0241.73005)]. Besides the nonlinear Hooke law is replaced by the integral correlation \[ t(x) = \int\limits_V \alpha(| x'-x| ,\tau)\sigma(x')\,dv(x'), \] where \(\sigma(\cdot)\) is a linear strain ...
