This problem book is a companion volume to the 2nd edition of the book "Building Physics: From Physical Principles to International Standards". The primary book offers a comprehensive presentation of the most important phenomena in building physics: heat transfer, moisture/humidity, sound/acoustics and illumination. The problem book includes both problems and solutions. Most of the problems are as practical as possible, while remaining conceptual and avoiding overreach. Many of the solutions presented do not simply end upon determination of the correct answer, but include further explanations for a deeper understanding of the theory and/or connections to other everyday phenomena. These explanations can be of great value to lecturers who use the primary book for their courses. All solutions are cross-referenced to the formulas or explanations in the primary book. This establishes the connection between theory and practice and contributes to a more thorough understanding of the subject. The book is primarily intended for lecturers and students of all subjects related to building physics.

This book offers new insights into the process of adjusting nanostructures in high-strength steels to achieve enhanced mechanical properties. It summarizes the state-of-the-art nanoengineering approaches, such as precipitation engineering, interface engineering, and short-range ordering engineering. The book explores the nanostructure-process-property relationships in various high-strength steels, including TRIP/TWIP/MBIP in high-Mn steels (HMnS), medium-Mn steels (MMnS), bearing steels, tool steels, and more. The author investigates a novel approach to control the phase transformation process during deformation and/or thermal treatment in steels, employing both experimental and theoretical tools.

This book provides a comprehensive overview of the mechanical distinctions between fretting damage under axial or bending external forces and fretting damage under a torsional load. It emphasizes the importance of studying practical accident cases to efficiently acquire technical skills. The book is structured around the fundamental technologies of material science, tribology, and mechanics, which are vital for understanding and addressing technical issues. The author has incorporated all fretting countermeasure technologies, which were previously often sensory and empirical in nature, and repositioned them as technologies grounded in fundamental principles. The book proposes an economical approach to product operation that maintains reliability by integrating not only design technology but also maintenance practices.It delves into specific materials, such as titanium alloys and aluminum alloys, which have seen increased use for weight reduction in industries like aerospace.In this book, ¿Critical Distance Stress Theory¿ that can easily derive the fatigue limit and fatigue life of the stress singular field at the contact edge was presented. As a result, the fretting fatigue strength and life can be predicted from the same FEM stress analysis as the normal stress concentration part.And finally, introducing a novel fretting mechanical model, the book focuses on scenarios where pressure force (N) and repeated tangential force (F) are applied to two planar objects, with the tangential force being transmitted solely through friction at the contact surface. This model finds relevance in turbine blade connection structures, among other applications. The author references Asai's research example, which encompasses fretting mechanical analysis, fretting wear evaluation, fatigue assessment, and structural damping evaluation using this model.

The book is devoted to the retirement of Prof. Wilfried Becker¿a liber amicorum for a well-known specialist in the field of structural mechanics. Many excellent scientists from institutions around the world wrote their scientific chapters, stressing the Becker¿s influence to structural mechanics. Thus, this collection discusses a lot of important problems and applications of mechanics.
