| finite element buckling analysis: Finite element theory and its application with open source codes Anthony Pickett, 2020-11-10 This book combines essential finite element (FE) theory with a set of fourteen tutorials using relatively easy-to-use open source CAD, FE and other numerical analysis codes so a student can undertake practical analysis and self-study. The theory covers fundamentals of the finite element method. Formulation of element stiffness for one dimensional bar and beam, two dimensional and three dimensional continuum elements, plate and shell elements are derived based on energy and variational methods. Linear, nonlinear and transient dynamic solution methods are covered for both mechanical and field analysis problems with a focus on heat transfer. Other important theoretical topics covered include element integration, element assembly, loads, boundary conditions, contact and a chapter devoted to material laws on elasticity, hyperelasticity and plasticity. A brief introduction to Computational Fluid Dynamics (CFD) is also included. The second half of this book presents a chapter on using tutorials containing information on code installation (on Windows) and getting started, and general hints on meshing, modelling and analysis. This is then followed by tutorials and exercises that cover linear, nonlinear and dynamic mechanical analysis, steady state and transient heat analysis, field analysis, fatigue, buckling and frequency analysis, a hydraulic pipe network analysis, and lastly two tutorials on CFD simulation. In each case theory is linked with application and exercises are included for further self-study. For these tutorials open source codes FreeCAD, CalculiX, FreeMAT and OpenFOAM are used. CalculiX is a comprehensive FE package covering linear, nonlinear and transient analysis. One particular benefit is that its format and structure is based on Abaqus, so knowledge gained is relevant to a leading commercial code. FreeCAD is primarily a powerful CAD modelling code, that includes good finite element meshing and modelling capabilities and is fully integrated with CalculiX. FreeMAT is used in three tutorials for numerical analysis demonstrating algorithms for explicit finite element and CFD analysis. And OpenFOAM is used for other CFD flow simulations. The primary aim of this book is to provide a unified text covering theory and practice, so a student can learn and experiment with these versatile and powerful analysis methods. It should be of value to both finite element courses and for student self-study. |

MATLAB is a high-level language specially designed for dealing with matrices, making it particularly suited for programming the finite element method, while Abaqus is a suite of commercial finite element software. Includes more than 100 tables, photographs, and figures Provides MATLAB codes to generate contour plots for sample results Introduction to Finite Element Analysis Using MATLAB and Abaqus introduces and explains theory in each chapter, and provides corresponding examples. It offers introductory notes and provides matrix structural analysis for trusses, beams, and frames. The book examines the theories of stress and strain and the relationships between them. The author then covers weighted residual methods and finite element approximation and numerical integration. He presents the finite element formulation for plane stress/strain problems, introduces axisymmetric problems, and highlights the theory of plates. The text supplies step-by-step procedures for solving problems with Abaqus interactive and keyword editions. The described procedures are implemented as MATLAB codes and Abaqus files can be found on the CRC Press website. |
| finite element buckling analysis: Metal-Ceramic Interfaces M. Rühle, A.G. Evans, J.P. Hirth, Michael F. Ashby, 2013-10-22 As engineering materials and structures often contain a metal or metallic alloy bonded to a ceramic, the resultant interface must be able to sustain mechanical forces without failure. They also play an important role in oxidation or reduction of materials. The workshop on 'Bonding, Structure and Mechanical Properties of Metal/Ceramic Interfaces' was held in January 1989 within the Acta/Scripta Metallurgica conference series. It drew together an international collection of 70 scientists who discussed a wide range of issues related to metal-ceramic interfaces. The sessions were divided into 7 categories: structure and bonding, chemistry at interfaces, formation of interfaces, structure of interfaces, thermodynamics/atomistics of interface fracture, mechanics of interface cracks, and fracture resistance of bimaterial interfaces. Within these headings attention was paid to grain boundaries, the influence of chemical processes on the behaviour of interfaces, diffusion bonding, characterization of fracture, and crack propagation by fatigue and by stress corrosion. The book presents a useful reference source for materials scientists, physicists, chemists, and mechanical engineers who are concerned with the roles and properties of interfaces. |
