Finite Element Analysis

by Richard H. King

Overview

King's FINITE ELEMENT ANALYSIS WITH SOLIDWORKS SIMULATION combines presentation theory with solid mechanics calculations to confirm students' configurations. This innovative approach explains concepts using examples and investigations that equip students for a range of applications. The author demonstrates calculations in PTC Mathcad, providing an interactive "what-if" environment. Students then build SOLIDWORKS Simulations. The book emphasizes the fundamentals with a focus on 3D analysis of real-world designs. Students learn critical concepts such as singular stiffness matrices, digital resolution, and rigid-body motion. They build a small FEA software program in PTC Mathcad that implements a 1D spring model. Investigations explore the effects of changing analyses as students compare solutions, identify errors, make decisions, and explore alternative configurations and new models.

About the Author

Dr. King is an Emeritus Professor of Mechanical Engineering at the Colorado School of Mines. He has a BS in mining engineering and a BS in geological engineering from the University of Utah and an MS and PhD in mining engineering from the Pennsylvania State University. He has worked in industry, for a government agency, and at a national lab in addition to his academic appointments at Penn State and the Colorado School of Mines, where he has taught since 1981. Dr. King's scholarly work integrates automated measurement systems and modeling in a variety of subject areas including mobile robotics, automated regolith handling, bat-habitat microclimates, and automated mine equipment and systems. A recent success was accurate prediction of a structural failure in a NASA lunar excavator with a finite element model. Working with faculty colleagues and graduate students, Dr. King has written more than 150 publications and a textbook, Introduction to Data Acquisition with LabVIEW, 2nd Edition. Dr. King's work also includes the development of the award-winning Multidisciplinary Engineering Laboratory course sequence. In addition to automated measurement systems, the course focuses on enhancing thinking maturity, open-ended problem solving, self-learning, writing skills, and teamwork. Dr. King has taught more than 30 different courses in several disciplines during his 40-year academic career. The most recent course is an introductory finite elements course, called Computer-Aided Engineering.

Editorial Reviews

"For senior undergraduate students, it is written in a very appropriate language and logic. For practical examples, this new book is much clearer in presentation. I love the example problems."

"I think the topics are in a very clear and logical order. The language was appropriately technical such that any junior who has taken statics and mechanics of materials would be able to fully understand. The author uses enough detail such that the students should fully understand what they are doing. I found the writing style to work well with this topic. This book does give much more theoretical background to help motivate what is being done. For most students, this should not impact the clarity, and in fact should improve the clarity assuming they understood statics and mechanics principles. I like that the beam example is used throughout, but then other examples are used later in the chapters. I could see this being a great book for continuing education."

"The method to present the problem and how to solve them is good. The examples are really clear, and the students can follow them easily."
