Chapter Chapter 3 in Questions About Elastic Waves, 2015, pp 19-42 from Springer

Abstract: Abstract In Chap. 2, questions about the essence of waves were asked and answers given. On the other hand, every wave Wave needs a medium to propagate. That is why it 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 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.
