Böcker av Christian Mittelstedt

This book follows the classical division of engineering mechanics as it is taught at technical colleges and universities and is dedicated to dynamics, i.e. the consideration of movements of bodies under forces. The aim of this book is to provide students with a clear introduction to dynamics and to enable them to formulate and solve engineering problems independently. The book provides a number of examples for this purpose. This book is aimed at students at technical colleges and universities of mechanical engineering, civil engineering, mechanics and all other degree programmes in which dynamics plays a role.

This book contains an introduction to the fundamental principles of the theory of stability of elastic bodies and structures. Beginning with very basic explanations of stability problems, this book starts with the treatment of systems of rigid beams, before beams under normal force and bending as well as the classical field of beam buckling are treated. For the case of beam buckling, an energetic consideration then follows, which forms the basis for a series of approximation methods. In addition to beam buckling, the stability cases of lateral-torsional buckling and lateral buckling are also of fundamental importance, to each of which a separate chapter is dedicated. This is followed by a discussion of plate buckling, and the book concludes with an introduction to shell buckling. This book is aimed at students at technical colleges and universities, as well as engineers in practice and researchers in the engineering sciences.

Das vorliegende Buch widmet sich der Elastostatik, d.h. der Ermittlung von Spannungen und von Deformationen in elastischen Körpern, und stellt eine umfangreiche Aufgabensammlung mit vollständigen Lösungen bereit. Studierende werden hiermit in die Lage versetzt, sich der Thematik anhand von durchgerechneten Beispielen zu nähern und darauf aufbauend ingenieurstechnische Aufgabenstellungen der Elastostatik eigenständig zu lösen. Das Buch wendet sich an Studierende an Fachhochschulen und Universitäten derjenigen Studiengänge, in denen die Elastostatik eine Rolle spielt.

This book deals with the analysis of plates and shells and is divided into four sections. After briefly introducing the basics of elasticity theory and the energy methods of elastostatics in the first section, the second section is devoted to the statics of disk structures. In addition to isotropic disks in Cartesian and polar coordinates, approximation methods and anisotropic disks are also discussed. The following third section deals with plate structures, covering plates in Cartesian and polar coordinates, and also discussing approximation methods and higher-order plate theories. Other chapters in this section discuss plate buckling as well as geometric nonlinear analysis and laminated plates. The fourth and final section of this book is devoted to shells, i.e., curved thin structures, following the common division into membrane theory on the one hand and bending theory on the other hand. This book is intended for students at universities, but also for engineers in practice andresearchers in engineering science.

This book follows the classical division of engineering mechanics as taught at universities in Germany and is devoted to strength of materials, i.e. the determination of stresses and of deformations in elastic bodies. The aim of this book is to provide students with a clear introduction and to enable them to formulate and solve engineering problems in this field. For this purpose, the book provides a number of examples. This book is intended for university students of mechanical engineering, civil engineering, mechanics, but also all other courses in which the contents of this book play a role.
