The book "Non-classical shell theory and its application to solving engineering problems" by Gulyaev V. and . and his colleagues is a fascinating and in-depth study that opens up new horizons in the field of mechanics and engineering. If you are an engineer, a student, a graduate student or just interested in modern approaches to solving complex problems in mechanics, this book will be a real discovery for you. The authors focus on non-classical shell theory, which is an important aspect of the mechanics of materials and structures. Shells are structures that are small in thickness compared to other sizes and are widely used in construction, aviation, shipbuilding and many other areas. However, traditional methods of their analysis are often insufficient to accurately describe the behavior of such complex systems. Gulyaev and his team propose new approaches that allow more accurate modeling and prediction of the behavior of shells under the influence of various loads and operating conditions. The book is divided into several parts, each of which is devoted to certain aspects of shell theory. The authors not only outline the theoretical foundations, but also offer practical examples, which makes the material accessible and understandable. Readers will be able to see how non-classical theory is used to solve real engineering problems, which gives the book practical value. The topics raised in the book cover a wide range of issues, from shell stability analysis to their dynamic behavior. The authors also consider the impact of various factors, such as geometry, material, and load conditions, on shell characteristics. This makes the book relevant for professionals working in the field of design and analysis of structures, as well as for students studying mechanical systems. Who can like this work? First of all, the book will be of interest to students and graduate students of technical specialties who want to deepen their knowledge in the field of mechanics and engineering . Practitioners working in construction, aviation or other industries will also find useful ideas and solutions for their projects in it. In addition, researchers involved in shell theory and related disciplines will appreciate the contribution of the authors to the development of this field. The style of Gulyaev and his co-authors is distinguished by clarity and logical presentation .. They skillfully combine theory with practical examples, which makes reading not only useful, but also fascinating. The book is written taking into account the latest achievements of science and technology, which makes it relevant in the rapidly changing world of engineering. If you are looking for literature on mechanics, shell theory, or engineering calculations, then "Non-classical shell theory and its application to engineering problems" will be a great addition to your library. This work will not only expand your knowledge, but also inspire new ideas and solutions in your professional activities. Do not miss the opportunity to get acquainted with this unique book, which will help you to look at the usual things from a new side and will open the world of modern engineering solutions before you.
