Abstract

The response of materials and structures against loads under dynamic conditions requires an understanding of transient regimes, with time being a key factor. For this purpose, it is highly important to be aware of how loads propagate through solids. This chapter introduces the reader to the concept of stress waves in solids. It includes a brief description of the basic concepts that govern most of the situations about propagation of stresses inside solid materials. Due to reasons of space, it offers only a limited view and only the fundamentals. For a deeper study, the reader may focus on other classical books that examine such fundamentals in greater depth. This chapter provides the basis of one-dimensional wave propagation of elastic waves, the boundary effects and reflection and transmission to a different media, and the classical representation of waves in bars. In addition, it provides a short introduction to plastic waves. Finally, it offers an introduction to three-dimensional waves in solids where the main aspects to consider include wave dispersion concepts.
