Die Balkentheorie erster Ordnung dient in der Elastostatik zur Berechnung von Spannungen und Verformungen an einem Balken. Dabei wird in die Timoshenko- (Theorie des schubweichen Balkens) und Euler-Bernoulli-Balkentheorie (Theorie des schubstarren Balkens) unterschieden. Mit Kenntnis der Spannungen und Verformungen können weiterführende Berechnungen, wie z. B. ein Festigkeitsnachweis, und die Auslegung von Balken durchgeführt werden. Die dazu notwendigen Modellannahmen und die entsprechenden Herleitungen werden in diesem essential verständlich und anwendungsgerecht dargestellt. Der Inhalt Grundgleichungen der Elastostatik Herleitung der Timoshenko-Balkentheorie Herleitung der Euler-Bernoulli-Balkentheorie Anwendungsbeispiele Die Zielgruppen Studierende des Maschinenbaus und ingenieurwissenschaftlicher Fächer Ingenieure in der Industrie Der Autor Prof. Dr.-Ing. Christian Spura lehrt an der Hochschule Hamm-Lippstadt Maschinenelemente, Getriebetechnik und Technische Mechanik.

This book presents in detail an alternative approach to solving problems involving both linear and nonlinear oscillations of elastic distributed parameter systems. It includes the so-called variational, projection and iterative gradient methods, which, when applied to nonlinear problems, use the procedure of linearization of the original non-linear equations. These methods are not universal and require a different solution for each problem or class of problems.However, in many cases the combination of the methods shown in this book leads to more efficient algorithms for solving important applied problems.To record these algorithms in a unified form, the first part of the book and its appendix devote considerable attention to compiling the general operator equations, which include (as particular cases) equations for vibrations in rods, plates, shells and three-dimensional bodies. They are mainly considered to be periodic or nearly periodic oscillations, which correspond to stationary or nearly stationary regimes of machinery operation. In turn, the second part of the book presents a number of solutions for selected applications. .

This book combines a model reduction technique with an efficient parametrization scheme for the purpose of solving a class of complex and computationally expensive simulation-based problems involving finite element models. These problems, which have a wide range of important applications in several engineering fields, include reliability analysis, structural dynamic simulation, sensitivity analysis, reliability-based design optimization, Bayesian model validation, uncertainty quantification and propagation, etc. The solution of this type of problems requires a large number of dynamic re-analyses. To cope with this difficulty, a model reduction technique known as substructure coupling for dynamic analysis is considered. While the use of reduced order models alleviates part of the computational effort, their repetitive generation during the simulation processes can be computational expensive due to the substantial computational overhead that arises at the substructure level. In this regard, an efficient finite element model parametrization scheme is considered. When the division of the structural model is guided by such a parametrization scheme, the generation of a small number of reduced order models is sufficient to run the large number of dynamic re-analyses. Thus, a drastic reduction in computational effort is achieved without compromising the accuracy of the results. The capabilities of the developed procedures are demonstrated in a number of simulation-based problems involving uncertainty.
