The Applied Theory of Elasticity . H. 1" by B. T. Sapunova is a fascinating and deep immersion in the world of mechanics and materials science, which will become an indispensable assistant for students, graduate students and specialists working in the field of engineering and applied physics. This work offers readers a unique look at the theory of elasticity, revealing its basic principles and practical application in various industries. In the first part of the book, the author begins with the basics, gradually introducing the reader to complex concepts, such as tension and deformation, as well as their interrelation. Sapunov not only expounds theoretical aspects, but also supports them with practical examples, which makes the material accessible and understandable. It seeks to explain how these principles apply to real-world engineering tasks, from building design to creating new materials. Readers will be able to see how theoretical knowledge becomes the basis for practical solutions, which makes the book especially valuable for those who want to not only learn, but also apply their knowledge in practice. The book will be of interest not only to students of technical specialties, but also to practicing engineers who want to refresh their knowledge or deepen their understanding of the theory of elasticity. It is also suitable for those who are interested in physics and mechanics, as well as those who plan to engage in scientific research in these areas. Given the complexity and importance of the topics addressed in the book, it can be an excellent addition to the training courses in mechanics and materials science. Topics raised in the "Applied Theory of Elasticity" cover a wide range of issues, such as the behavior of materials under the influence of various loads, methods of calculation and analysis, as well as modern approaches to solving engineering problems. Sapunov emphasizes the importance of understanding the physical processes occurring in materials, which allows engineers to make more informed decisions in the design and operation of structures. The author's style is distinguished by clarity and logical presentation, which makes even the most complex topics accessible to understanding. In. T. Sapunov is a well-known specialist in the field of mechanics, and his experience and knowledge are reflected in every page of the book.
