This book is based on lectures I have given in recent years in the field of stability theory and lightweight engineering. While writing the treatise, I paid great attention to always presenting the theoretical correlations clearly and correctly and introducing the reader not only to the how? but also to the why?, but at the same time to fill the topics discussed with life and not to present them too dryly to the readers. I hope that I have managed this balancing act between theory and practical applicability. So why a book about this specific field of knowledge? Engineers in many fields, such as civil engineering, mechanical engineering or aerospace engineering, but also and above all general lightweight engineering, are very often confronted with stability problems such as flexural buckling, flexural-torsional buckling and lateral buckling of beam structures and buckling of plate and shell structures. Especially with the very slender and thin- walled structures found in aircraft construction, for example, the stability behavior and the safe design against stability failure of the components are often in the foreground, so that a detailed consideration of the problems dealt with here is more than justified. The focus of this book is on the analytical treatment of stability problems, whether in an exact manner or by applying elementary approximation methods, as they still have considerable practical relevance today. Purely numerical methods such as the finite element method, which have become an integral part of the daily work of engineers, are also touched on for beam structures, but for purely didactic reasons these cannot be dealt with in the appropriate depth in this book which understands itself as an introductory text to the topic of elastic stability of structures. The content of this book is based on the contents of my lectures ‘Lightweight Engineering 1+2’ and ‘Theory of Elastic Stability’, which I hold for students of the Master’s degree programs in Mechanical Engineering and Aerospace Engineering, as well as other degree programs at the Technical University of Darmstadt. The book is the continuation of a series of books on the analysis methods of lightweight engineering, which began in 2021 with the book ‘Structural Mechanics in Lightweight Engineering’ and continued in 2022 with the book ‘Theory of Plates and Shells’.
