This comprehensive textbook focuses on the torsion in thin walled structures, highlights the nuances of the problems faced and succinctly discusses warping, bimoment, etc. Since in several thin walled structures, torsion is the only or dominant loading, this book addresses such unique structures as well. It provides a concise explanation of the warping properties and how they are evaluated. Thin walled structures with torsion as the preponderant loading are then treated using classical and ¿nite element methods. No prior knowledge of the ¿nite element method is required as the method is introduced from the basics. The same problem is worked out by both approaches so that the concepts are clearly understood by the readers. The book includes pedagogical features such as end-of-chapter questions and worked out examples to augment learning and self-testing. The book will be useful for graduate courses as well as for professional development coursework for structural engineersin the aerospace, mechanical, and civil engineering domains.

Proposed in the early 1990s, the enhanced assumed strain (EAS) method is one of the probably most successful mixed finite element methods for solid mechanics. This cumulative dissertation gives a comprehensive overview of previous publications on that method and covers recent improvements for EAS elements. In particular, we describe three key issues of standard EAS elements and develop corresponding solutions.

This book is written by subject experts based on the recent research results in steel plate shear walls considering the gravity load effect. It establishes a vertical stress distribution of the walls under compression and in-plane bending load and an inclination angle of the tensile field strip. The stress throughout the inclined tensile strip, as we consider the effect of the vertical stress distribution, is determined using the von Mises yield criterion. The shear strength is calculated by integrating the shear stress along the width. The proposed theoretical model is verified by tests and numerical simulations. Researchers, scientists and engineers in the field of structural engineering can benefit from the book. As such, this book provides valuable knowledge, useful methods, and practical algorithms that can be considered in practical design of building structures adopting a steel shear wall system.

Stochastic elasticity is a fast developing field that combines nonlinear elasticity and stochastic theories in order to significantly improve model predictions by accounting for uncertainties in the mechanical responses of materials. However, in contrast to the tremendous development of computational methods for large-scale problems, which have been proposed and implemented extensively in recent years, at the fundamental level, there is very little understanding of the uncertainties in the behaviour of elastic materials under large strains.Based on the idea that every large-scale problem starts as a small-scale data problem, this book combines fundamental aspects of finite (large-strain) elasticity and probability theories, which are prerequisites for the quantification of uncertainties in the elastic responses of soft materials. The problems treated in this book are drawn from the analytical continuum mechanics literature and incorporate random variablesas basic concepts along with mechanical stresses and strains. Such problems are interesting in their own right but they are also meant to inspire further thinking about how stochastic extensions can be formulated before they can be applied to more complex physical systems.

For the first time, the Micropolar Theory of Elasticity is applied to solving a wide variety of problems connected to the specifics of nanomaterials. Namely, their unique physical-mechanical characteristics and behaviors under various stress-induced conditions.These theories have been constructed based on the equations of the classical theory of elasticity as well as other equations that have till now remained untouched in their application to molecular theories of solid deformable media. The book also introduces a new applied micropolar theory of thin shells which is based on Cosserat's pseudo-continuum. It explores the theory's application to a category of nanomaterial shells and plates previously neglected from classical theories due to their unconventional size and structure. Theoretical results are accompanied by solutions of certain problems, essential for various applications.The book consists of six chapters. The first chapter is a review of the essentialdata on the non-symmetric theory of elasticity. The second and third chapters are devoted to various theories of plate bending and solutions to some basic problems. Chapter four refers to membrane or, so-called, momentary shell theory. Chapter five deals with the theory of very shallow shells. Finally, chapter six presents the geometry of the nonlinear theory of plates and the theory of very shallow shells.The book is intended for researchers, postgraduate students, and engineers, interested in the design of structures from nanomaterials and in the problems of mechanics of deformable bodies, theories of shells and plates, and their applications in micromechanics.
