This book deals with the Finite Element Method for the analysis of elastic structures such as beams, plates, shells and solids. The modern approach of Unified Formulation (UF), as proposed by the lead author, deals with the consideration of one-dimensional (beams), two-dimensional (plates and shells) and three-dimensional (solids) elements. Applications are given for structures which are typically employed in civil, mechanical, and aerospace engineering fields. Additional topics include mixed order elements, extension to layered composite structures, and the analysis of multifield problems involving mechanical, electrical and thermal loadings.

In recent years, bridge engineers and researchers are increasingly turning to the finite element method for the design of Steel and Steel-Concrete Composite Bridges. However, the complexity of the method has made the transition slow. Based on twenty years of experience, Finite Element Analysis and Design of Steel and Steel-Concrete Composite Bridges provides structural engineers and researchers with detailed modeling techniques for creating robust design models. The book’s seven chapters begin with an overview of the various forms of modern steel and steel–concrete composite bridges as well as current design codes. This is followed by self-contained chapters concerning: nonlinear material behavior of the bridge components, applied loads and stability of steel and steel–concrete composite bridges, and design of steel and steel–concrete composite bridge components. Constitutive models for construction materials including material non-linearity and geometric non-linearity. + The mechanical approach including problem setup, strain energy, external energy and potential energy), mathematics behind the method.  + Commonly available finite elements codes for the design of steel bridges. + Explains how the design information from Finite Element Analysis is incorporated into Building information models to obtain quantity information, cost analysis.

    J. N. Reddy ... 768 pages - Publisher: Oxford Univ. Press; 2nd edition (January, 2015) ... Language: English - ISBN-10: 0199641757 - ISBN-13: 978-0199641758 ...

    The second edition of An Introduction to Nonlinear Finite Element Analysis has the same objective as the first edition, namely, to facilitate an easy and thorough understanding of the details that are involved in the theoretical formulation, finite element model development, and solutions of nonlinear problems. The book offers an easy-to-understand treatment of the subject of nonlinear finite element analysis, which includes element development from mathematical models and numerical evaluation of the underlying physics. The new edition is extensively reorganized and contains substantial amounts of new material. Chapter 1 in the second edition contains a section on applied functional analysis. Chapter 2 on nonlinear continuum mechanics is entirely new. Chapters 3 through 8 in the new edition correspond to Chapter 2 through 8 of the first edition, but with additional explanations, examples, and exercise problems. Material on time dependent problems from Chapter 8 of the first edition is absorbed into Chapters 4 through 8 of the new edition. Chapter 9 is extensively revised and it contains up to date developments in the large deformation analysis of isotropic, composite and functionally graded shells. Chapter 10 of the first edition on material nonlinearity and coupled problems is reorganized in the second edition by moving the material on solid mechanics to Chapter 12 in the new edition and material on coupled problems to the new chapter, Chapter 10, on weak-form Galerkin finite element models of viscous incompressible fluids. Finally, Chapter 11 in the second edition is entirely new and devoted to least-squares finite element models of viscous incompressible fluids. Chapter 12 of the second edition is enlarged to contain finite element models of viscoelastic beams. In general, all of the chapters of the second edition contain additional explanations, detailed example problems, and additional exercise problems. Although all of the programming segments are in Fortran, the logic used in these Fortran programs is transparent and can be used in Matlab or C++ versions of the same. Thus the new edition more than replaces the first edition, and it is hoped that it is acquired by the library of every institution of higher learning as well as serious finite element analysts.

    This book presents the theory and computer implementations of the finite element method as applied to nonlinear problems of heat transfer and similar field problems, fluid mechanics (flows of incompressible fluids), and solid mechanics (elasticity, beams and plates). Both geometric as well as material nonlinearities are considered, and static and transient (i.e.: time-dependent) responses are studied. Although there exist a number of books on nonlinear finite elements that serve as good references for engineers who are familiar with the subject and wish to learn advanced topics or the latest developments, there is currently no book which is suitable as a textbook for a first course on nonlinear finite element analysis. This book fills the void in the market, providing a clear understanding of the concepts of nonlinear finite element analyses through detailed theoretical formulations and computer implementation steps, examples and exercises. In addition, the book serves as a prelude to more advanced books on the subject.

    GEO5 Finite Element Method Analysis [Size: 48 MB] ... The FEM software program allows solution of general geotechnical tasks using the Finite Element Method. The modeling capabilities include the analysis of underground structures, tunnels and dams in addition to stability and water flow analysis. Adopting the Finite Element Method not only gives the user a broader insight into the analyzed structures, it provides verification of the results from classical methods. Application of the Finite Element Method in structural analysis is substantially more demanding in comparison to modeling approaches based on analytical methods. However, the modules contain a number of features (topology corrector, finite element mesh generator) which considerably simplify preparation of the computational model. The analysis provides information about the deformed shape of structures, distribution of stresses and location of plastic zones inside the soil body, internal forces developed in beams, anchors and geo-reinforcements. Performing stability analysis then considerably extends the knowledge acquired from the application of classical methods. The FEM-Tunnel module serves to analyze underground structures, including tunnels constructed using the New Austrian Tunneling Method. An important feature is a built-in generator of lining, which can be placed anywhere in the soil body. Creating the computational model including the finite element mesh is fully automatic. This module also accounts for various non-mechanical actions such thermal loading, technological shrinkage, swelling of soils and also the definition of anchored regions. The FEM-Water Flow module determines, depending on water flow boundary conditions, the ground water table, distribution of pore water pressures, flow velocities and overall inflow/outflow. The results of water flow (seepage) analysis may be automatically introduced into the structural analysis including stability simulations. The FEM - Consolidation module is used to perform time dependent settlement analysis under foundations, embankments and surface loads (surcharges).

    Originally developed for mechanical and aeronautical engineering, structural optimization is not so easily applied to civil and architectural engineering, as structures in these fields are not mass products, but more often unique structures planned in accordance with specific design requirements. The shape and geometry of such structures are determined by a designer or an architect in view of nonstructural performance that includes aesthetics. Until now, books in this area gave little help to engineers working in cooperation with designers, as they covered conceptual material with little consideration of civil engineering applications, or they required a solid background in applied mathematics and continuum mechanics, an area not usually studied by practicing engineers and students in civil engineering. Optimization of Finite Dimensional Structures introduces methodologies and applications that are closely related to design problems encountered in structural optimization, to serve as a bridge between the communities of structural optimization in mechanical engineering and the researchers and engineers in civil engineering. This unparalleled, self-contained work: Provides readers with the basics of optimization of frame structures, such as trusses, building frames, and long-span structures, with descriptions of various applications to real-world problems. Summarizes the historical development of methodologies and theorems on optimization of frame structures. Introduces many recently developed highly efficient optimization techniques presented with illustrative examples. Describes traditional problems with constraints on limit loads, member stresses, compliance, and eigenvalues of vibration, all in detail. Offers a unique look at optimization results for spatial trusses and latticed domes. Mathematical preliminaries and methodologies are summarized in the book’s appendix, so that readers can attend to the details when needed without having to wade through tedious mathematics in the explanatory main chapters. Instead, small examples that can be solved by hand or by using a simple program are presented in these chapters, making the book readily accessible and highly useful for both classroom use and professional self-study.

    Jonathan Whiteley ... 232 pages - Publisher: Springer; 1st edition (January, 2017) ... Language: English - ISBN-10: 331949970X - ISBN-13: 978-3319499703 ...

    This book presents practical applications of the finite element method to general differential equations. The underlying strategy of deriving the finite element solution is introduced using linear ordinary differential equations, thus allowing the basic concepts of the finite element solution to be introduced without being obscured by the additional mathematical detail required when applying this technique to partial differential equations. The author generalizes the presented approach to partial differential equations which include nonlinearities. The book also includes variations of the finite element method such as different classes of meshes and basic functions. Practical application of the theory is emphasised, with development of all concepts leading ultimately to a description of their computational implementation illustrated using Matlab functions. The target audience primarily comprises applied researchers and practitioners in engineering, but the book may also be beneficial for graduate students.
