How to model waves?,t is essential to start with a description of media (materials). As mentioned in the Introduction, the focus in this book is on waves in solids. Except some comparative examples, waves in fluids or gases are excluded as well as electromagnetic waves. Also, we shall use the concept of continua. If fo

What are internal variables? , answers,stood and measured on the macrolevel. However, “there is no unique answer to the question how the microstructure influence can be accounted for in a continuum mechanical model” . In addition, thermodynamical constraints should be taken into account, which is not obvious in many theories. In the

What physical effects are involved?, Ian Stewart asks this question and gives the answer that “equations are the lifeblood of mathematics, science and technology”, and adds that “… they reveal deep and beautiful patterns and regularities”.

What are internal variables? , answers,ectly into modelling of dynamical phenomena is provided by the concept of internal variables. The idea of internal variables can be traced back to P. Duhem, P. Bridgman and J. Kestin (see historical overview in ). A contemporary presentation of the formalism of internal variables is presented by Maugin and Maugin and Muschik .

How to model waves?,t some comparative examples, waves in fluids or gases are excluded as well as electromagnetic waves. Also, we shall use the concept of continua. If for some reason or another, a discrete model (lattice model) is the starting point, continualization will be used in order to get to a continuous model.
