The basics of the dynamics of continuous media. are presented A unified view of this field of science is given, which should help the learner in his work on complex issues. When considering specific tasks, the focus is on models of the mechanics of a deformable solid. All material is accompanied by examples of solving specific problems with appropriate illustrations. Fundamental concepts are defined, the classification of dynamic processes is given. One-dimensional flat, spherical and cylindrical waves are considered, as well as one-dimensional dynamic processes in rods and thin plates. The solutions of initial problems for space and plane, stationary and non-stationary two-dimensional problems for semi-limited regions. are given. To facilitate reading, various models of continuous media are given, as well as information about generalized functions and their integral transformations.
