Description

Learn Basic Theory and Software Usage from a Single Volume

Finite Element Modeling and Simulation with ANSYS Workbench combines finite element theory with real-world practice. Providing an introduction to finite element modeling and analysis for those with no prior experience, and written by authors with a combined experience of 30 years teaching the subject, this text presents FEM formulations integrated with relevant hands-on applications using ANSYS Workbench for finite element analysis (FEA). Incorporating the basic theories of FEA and the use of ANSYS Workbench in the modeling and simulation of engineering problems, the book also establishes the FEM method as a powerful numerical tool in engineering design and analysis.

Include FEA in Your Design and Analysis of Structures Using ANSYS Workbench

The authors reveal the basic concepts in FEA using simple mechanics problems as examples, and provide a clear understanding of FEA principles, element behaviors, and solution procedures. They emphasize correct usage of FEA software, and techniques in FEA modeling and simulation. The material in the book discusses one-dimensional bar and beam elements, two-dimensional plane stress and plane strain elements, plate and shell elements, and three-dimensional solid elements in the analyses of structural stresses, vibrations and dynamics, thermal responses, fluid flows, optimizations, and failures. Contained in 12 chapters, the text introduces ANSYS Workbench through detailed examples and hands-on case studies, and includes homework problems and projects using ANSYS Workbench software that are provided at the end of each chapter.

  • Covers solid mechanics and thermal/fluid FEA
  • Contains ANSYS Workbench geometry input files for examples and case studies
  • Includes two chapters devoted to modeling and solution techniques, design optimization, fatigue, and buckling failure analysis
  • Provides modeling tips in case studies to provide readers an immediate opportunity to apply the skills they learn in a problem-solving context

Finite Element Modeling and Simulation with ANSYS Workbench benefits upper-level undergraduate students in all engineering disciplines, as well as researchers and practicing engineers who use the finite element method to analyze structures.

Reviews

"This book covers a wide range of engineering analyses using FEM with adequate theoretical background, illustrative examples, and detailed tutorials on using ANSYS Workbench for FEA. … It covers both the theoretical and practical parts of FEM, which is very helpful to engineering students."

—Anh-Vu Phan, Universtiy of South Alabama, Mobile, USA

"The book is an excellent resource to introduce undergraduate and graduate engineering students to Finite Element Analysis. A great deal of emphasis is made on the finite element methods through simple application examples. …The main thing that I like about this book is that the author has presented the material using ANSYS Workbench. For undergraduate students who are considered beginners with FE, this is the ideal software to use. The examples are simple and clear and the ANSYS Workbench Case Studies are good applications of the techniques."

—Dr. Mohammad H. Alimi, California State University, Fresno, USA

"This book should be a great resource for engineers or senior undergraduate students who want to learn FEA and use ANSYS themselves, and therefore can be adopted as a textbook for senior undergraduate students in engineering when introducing FEA."

—Ernian Pan, University of Akron, Ohio, USA

"This is the textbook I have long been looking for in my teaching of finite element analysis to undergraduate students. Teaching an undergraduate level finite element course is challenging due to the amount of mathematics and physics involved as well as the FEM’s vast applications in engineering, design and optimization. Very often, students are overwhelmed or discouraged by the theoretical and mathematical content of the course and, therefore, have difficulty or reluctance in utilizing the method in their engineering analysis and design. The balance of the FEM’s theoretical foundation and its application in engineering practice is achieved in an elegant way in this book."

—Gang Li, Department of Mechanical Engineering, Clemson University, South Carolina, USA

"Even though there are plenty of FEA books published, this one is really the textbook you need for the first FEA courses offered at 4-year universities. The theory and methodology parts are excellent, and the "Case Studies with ANSYS Workbench" sections at the end of every chapter are outstanding. With those case studies, the study of this course will become a joy instead of hard work."

—Daming Zhang, California State University, Fresno, USA
