| computer methods in applied mechanics and engineering: Continuum and Computational Mechanics for Geomechanical Engineers Ömer Aydan, 2021-04-20 The field of rock mechanics and rock engineering utilizes the basic laws of continuum mechanics and the techniques developed in computational mechanics. This book describes the basic concepts behind these fundamental laws and their utilization in practice irrespective of whether rock/rock mass contains discontinuities. This book consists of nine chapters and six appendices. The first four chapters are concerned with continuum mechanics aspects, which include the basic operations, definition of stress and strain tensors, and derivation of four fundamental conservation laws in the simplest yet precise manner. The next two chapters are the preparation for computational mechanics, which require constitutive laws of geomaterials relevant to each conservation law and the procedures for how to determine required parameters of the constitutive laws. Computational mechanics solves the resulting ordinary and partial differential equations. In Chapter 7, the methods of exact (closed-form) solutions are explained and they are applied to ordinary/partial differential equations with solvable boundary and initial conditions. In Chapter 8, the fundamentals of approximate solution methods are explained for one dimension first and then how to extend them to multi-dimensional problems. The readers are expected to learn and clearly understand how they are derived and applied to various problems in geomechanics. The final chapter involves the applications of the approximate methods to the actual problems in practice for geomechanical engineers, which cover the continuum to discontinuum, including the stress state of the earth as well as the ground motions induced by earthquakes. Six appendices are provided to have a clear understanding of continuum mechanics operations and procedures for how to deal with discontinuities/interfaces often encountered in rock mechanics and rock engineering. |

| computer methods in applied mechanics and engineering: Computational Structural Concrete Ulrich Häussler-Combe, 2022-09-22 Beton ist aufgrund seiner Vorteile der mit Abstand meistverwendete Baustoff: er ist formbar, preiswert und überall verfügbar. Kombiniert mit Bewehrung bietet dies eine immense Bandbreite an Eigenschaften und kann für eine Vielzahl von Zwecken angepasst werden. Damit ist Beton der Baustoff des 20. Jahrhunderts. Um der Baustoff des 21. Jahrhunderts zu sein, muss seine Nachhaltigkeit in den Fokus rücken. Bewehrte Betonkonstruktionen müssen mit geringerem Materialaufwand konstruiert werden, wobei ihr Tragfähigkeitspotential optimal ausgeschöpft werden muss. Computergestützte Methoden wie die Finite-Elemente-Methode (FEM) bieten wesentliche Werkzeuge, um das Ziel zu erreichen. In Kombination mit experimenteller Validierung ermöglichen sie ein tieferes Verständnis der Tragmechanismen. Im Vergleich zu herkömmlichen Ansätzen kann eine realistischere Abschätzung der Grenzzustände der Tragfähigkeit und der Gebrauchstauglichkeit erreicht werden. Dies ermöglicht eine deutlich verbesserte Ausnutzung der Baustoffe. Damit eröffnet sich auch ein weiterer Horizont für innovative Tragwerksentwürfe. Anspruchsvolle numerische Rechenverfahren werden aber in der Regel als Black Boxes bereitgestellt. Daten werden eingegeben, die Ausgaben ungeprüft übernommen, aber das Verständnis für die dazwischenliegenden Schritte ist oft rudimentär. Dies birgt die Gefahr von Fehlinterpretationen, um nicht zu sagen ungültigen Ergebnissen im Vergleich zu den getroffenen Problemdefinitionen. Das Risiko ist insbesondere bei nichtlinearen Problemen hoch. Bewehrter Beton weist als Verbundmaterial in seinen Grenzzuständen ein nichtlineares Verhalten auf, verursacht durch Verbund und nichtlineare Eigenschaften seiner Bestandteile. Seine Rissbildung ist ein reguläres Verhalten. In diesem Buch werden die Mechanismen des bewehrten Betons unter dem Blickwinkel numerischer Methoden aufgezeigt. So sollen auch Black Boxes transparent werden. Das Buch beschreibt entsprechende Methoden für Balken, Scheiben, Platten und Schalen im Rahmen von Quasi-Statik und Dynamik. Betonkriechen, Temperatureinwirkungen, Vorspannung, große Verformungen werden beispielhaft behandelt. Weiterhin werden aktuelle Materialmodelle für Beton dargestellt. Dabei werden sowohl die Möglichkeiten als auch die Fallstricke numerischer Methoden aufgezeigt. Die Theorie wird durch eine Vielzahl von Beispielen veranschaulicht. Die meisten von ihnen werden mit dem in Python implementierten und unter Open-Source-Bedingungen verfügbaren Softwarepaket ConFem durchgeführt. |

| computer methods in applied mechanics and engineering: Simulation of Manufacturing Sequences of Functionally Graded Structures Gleim, Tobias, 2017-02-10 The current paper establishes an axisymmetric model for an inductive heating process. Therein, the fully coupled MAXWELL equations, assuming a temperature dependent permeability, are combined with the non-linear heat conduction equation to yield a monolithic solution strategy. The latter is based on a consistent linearization together with a higher order finite element discretization using GALERKIN'S method in space. For the temporal discretization, the generalized Newmark-? methods, higher order RUNGE-KUTTA methods, and discontinuous and continuous GALERKIN methods are used. Furthermore, the residual error is introduced to open an alternative way to obtain a numerically efficient estimation of the time integration accuracy. Simulation results of the electric, magnetic and thermal fields are provided, together with parameter studies concerning spatial discretization, frequency dependence and penetration depth of the heating zone. Another topic analyzed is the residual error and its estimation quality regarding polynomial degree and time step size. A further aspect of this work is the investigation of the thermal fluid-structure interaction with respect to functionally graded materials. Different coupling strategies for the acceleration of the fixed-point iteration in each time step is in the foreground. Relaxation methods as well as extrapolation methods make it possible to significantly reduce the number of fixed point iterations. At the same time, an adaptive strategy with higher order RUNGE-KUTTA methods can provide a further advantage in combination with acceleration methods. |

| computer methods in applied mechanics and engineering: Structure-preserving Integrators in Nonlinear Structural Dynamics and Flexible Multibody Dynamics Peter Betsch, 2016-05-10 This book focuses on structure-preserving numerical methods for flexible multibody dynamics, including nonlinear elastodynamics and geometrically exact models for beams and shells. It also deals with the newly emerging class of variational integrators as well as Lie-group integrators. It discusses two alternative approaches to the discretization in space of nonlinear beams and shells. Firstly, geometrically exact formulations, which are typically used in the finite element community and, secondly, the absolute nodal coordinate formulation, which is popular in the multibody dynamics community. Concerning the discretization in time, the energy-momentum method and its energy-decaying variants are discussed. It also addresses a number of issues that have arisen in the wake of the structure-preserving discretization in space. Among them are the parameterization of finite rotations, the incorporation of algebraic constraints and the computer implementation of the various numerical methods. The practical application of structure-preserving methods is illustrated by a number of examples dealing with, among others, nonlinear beams and shells, large deformation problems, long-term simulations and coupled thermo-mechanical multibody systems. In addition it links novel time integration methods to frequently used methods in industrial multibody system simulation. |

| computer methods in applied mechanics and engineering: Separated Representations and PGD-Based Model Reduction Francisco Chinesta, Pierre Ladevèze, 2014-09-02 The papers in this volume start with a description of the construction of reduced models through a review of Proper Orthogonal Decomposition (POD) and reduced basis models, including their mathematical foundations and some challenging applications, then followed by a description of a new generation of simulation strategies based on the use of separated representations (space-parameters, space-time, space-time-parameters, space-space,...), which have led to what is known as Proper Generalized Decomposition (PGD) techniques. The models can be enriched by treating parameters as additional coordinates, leading to fast and inexpensive online calculations based on richer offline parametric solutions.
