The tutorials are suitable for either professional or student use. The lessons discuss linear static response for problems involving truss, plane stress, plane strain, axisymmetric, solid, beam, and plate structural elements. Example problems in heat transfer, thermal stress, mesh creation and transferring models from CAD solid modelers to ANSYS are also included. The tutorials progress from simple to complex. Each lesson can be mastered in a short period of time, and lessons 1 through 7 should all be completed to obtain a thorough understanding of basic ANSYS structural analysis. The concise treatment includes examples of truss, beam and shell elements completely updated for use with ANSYS APDL Printed in full color, it utilizes rich graphics and step-by-step instructions to guide you through learning how to perform finite element simulations using ANSYS Workbench.
Twenty seven real world case studies are used throughout the book. Many of these case studies are industrial or research projects that you build from scratch. Prebuilt project files are available for download should you run into any problems. Companion videos, that demonstrate exactly how to perform each tutorial, are also available. Relevant background knowledge is reviewed whenever necessary. To be efficient, the review is conceptual rather than mathematical. Key concepts are inserted whenever appropriate and summarized at the end of each chapter. Additional exercises or extension research problems are provided as homework at the end of each chapter. A learning approach emphasizing hands-on experiences is utilized though this entire book. A typical chapter consists of six sections. The first two provide two step-by-step examples. The third section tries to complement the exercises by providing a more systematic view of the chapter subject.
The following two sections provide more exercises. The final section provides review problems. Who this book is for This book is designed to be used mainly as a textbook for undergraduate and graduate students.

Figure P Figure P NOTES: Placed Features, Assembly Modeling Techniques Chapter 3 Modeling Techniques OVERVIEW This Chapter discusses modeling techniques that illustrate the flexibility inherent in the feature-based parametric modeling of DesignModeler. In parametric design modeling we wish to assign parameters to these quantities so that they can be varied to fit various design requirements. It is also possible to write equations that relate the required variation in certain parameters in terms of other parameters. For example, it might be important for a hole always to be centered in a bracket even if different designs require that the bracket width change with application. Tutorial 3A illustrates this use of parameters. DesignModeler is a full-featured parametric design modeling system that provides for importation of models from other CAD systems and also allows the user to export models to other CAD systems.
One vehicle for doing this is the use of the standard neutral file formats IGES Initial Graphics Exchange Specification and STEP Standard for the Exchange of Product Model Data , agreed upon standards for the transfer of models between systems. Modeling Techniques Parts in DesignModeler are composed of Bodies whereas Assemblies may be composed of Parts. We illustrate these concepts also in this Chapter. The part in question is shown in the figure below. Here we wish the long leg of the bracket always to be 1. The bracket thickness is to be constant. These invariant design requirements are accomplished using parametric relations in Designlvlodeler, 1.

iges or STEP SURFACE AND LINE MODELS Surface models are necessary if one wishes to perform analysis using simplified planar or 3D surface models instead of solids. Line models are needed when line elements are being used in engineering truss or beam simulations. The important shell plate engineering bending models are supported in Workbench DesignModeler by providing for the DesignModeler creation of surface models subsequently analyzed using ANSYS plate element technology. Beam bending is supported by the creation of line models to which beam cross sections are attached. Planar surface models are used to support analysis of Plane Stress, Plane Strain and Axisymmetric problems. Later we will use this same solid to create a three-dimensional surface model.

In many cases, analysts use the finite element method to perform parametric studies on potential designs to size parts, weed out less desirable design scenarios, and predict system behavior under load. In this book, we discuss common pitfalls encountered by many finite element analysts, in particular, students encountering the method for the first time. We present a variety of simple problems in axial, bending, torsion, and shear loading that combine the students' knowledge of theoretical mechanics, numerical methods, and approximations particular to the finite element method itself. We also present case studies in which analyses are coupled with experiments to emphasize validation, illustrate where interpretations of numerical results can be misleading, and what can be done to allay such tendencies. Challenges in presenting the necessary mix of theory and applications in a typical undergraduate course are discussed. We also discuss a list of tips and rules of thumb for applying the method in practice.
Essentials of the Finite Element Method explains the basics of FEM, then relates these basics to a number of practical engineering applications. Specific topics covered include linear spring elements, bar elements, trusses, beams and frames, heat transfer, and structural dynamics. Throughout the text, readers are shown step-by-step detailed analyses for finite element equations development. The text also demonstrates how FEM is programmed, with examples in MATLAB, CALFEM, and ANSYS allowing readers to learn how to develop their own computer code. Provides complete and unified coverage of the fundamentals of finite element analysis Covers stiffness matrices for widely used elements in mechanical and civil engineering practice Offers detailed and integrated solutions of engineering examples and computer algorithms in ANSYS, CALFEM, and MATLAB.
