Preface of Mechanical Design of Machine Components
This Mechanical Design of Machine Components by Ansel C.Ugural book developed from classroom notes prepared in connection with junior-senior undergraduate and first-year graduate courses in mechanical design, machine design, mechanical engineering design, and engineering design and analysis.
The scope of this Mechanical Design of Machine Components by Ansel C.Ugural book is wider than any other book on the subject.
In addition to its applicability to ¬mechanical engineering, and to some extent, aerospace, agricultural, and nuclear engineering and applied engineering mechanics curricula, I have endeavored to make the book useful to practicing engineers as well.
The Mechanical Design of Machine Components by Ansel C.Ugural book offers a simple, comprehensive, and methodical presentation of the fundamental concepts and principles in the design and analysis of machine components and basic structural members.
The coverage presumes knowledge of the mechanics of materials and material properties.
However, topics that are particularly significant to understanding the subject are reviewed as they are taken up.
Special effort has been made to present a Mechanical Design of Machine Components by Ansel C.Ugural book that is as self-explanatory as possible, thereby reducing the work of the instructor.
The presentation of the material in this Mechanical Design of Machine Components by Ansel C.Ugural book strikes a balance between the theory necessary to gain insight into mechanics and the design methods.
I, therefore, attempt to stress those aspects of theory and application that prepare a student for more advanced study or professional practice in design.
Above all, I have made an effort to provide a visual interpretation of equations and present the material in a form useful to a diverse audience.
The analysis presented should facilitate the use of computers and programmable calculators.
The commonality of the analytical methods needed to design a wide variety of elements and the use of computer-aided engineering as an approach to design are emphasized.
Mechanical Design of Machine Components provides unlimited opportunities for the use of computer graphics.
Computer solutions are usually preferred because the evaluation of design changes and “what-if” analyses require only a few keystrokes.
Hence, many examples, case studies, and problems in the Mechanical Design of Machine Components by Ansel C.Ugural book are discussed with the aid of a computer.
Generally, solid modeling serves as a design tool that can be used to create finite element (FE) models for analysis and dynamic simulation.
Instructors may use a simple PC-based FE program to give students exposure to the method applied to stress concentration and axisymmetrically loaded and plane stress problems.
The website for the Mechanical Design of Machine Components by Ansel C.Ugural book (see Optional Media Supplements) allows the user to treat problems more realistically and demonstrates the elements of good computational practice.
The Mechanical Design of Machine Components by Ansel C.Ugural book is independent of any software package. Traditional analysis in design, based on the methods of mechanics of materials, is given full treatment. In some instances, the methods of the applied theory of elasticity are employed.
The role of the theory of elasticity in this Mechanical Design of Machine Components by Ansel C.Ugural book is threefold: It places limitations on the application of the mechanics of materials theory,
It is used as the basis of FE formulation, and it provides exact solutions when configurations of loading and component shape are simple.
Plates, shells, and structural members are discussed to enable the reader to solve real-life problems and understand interactive case studies.
Website addresses of component and equipment manufacturers and open-ended web problems are given in many chapters to provide the reader access to additional information on those topics.
Also presented is finite element analysis (FEA) in computer-aided design. The foregoing unified methods of analysis give the reader the opportunity to expand his or her ability to perform the design process in a more realistic setting.
The Mechanical Design of Machine Components by Ansel C.Ugural book attempts to fill what I believe to be a void in the world of textbooks on machine design.
The Mechanical Design of Machine Components by Ansel C.Ugural book is divided into three sections.
The basics of loading, stress, strain, materials, deflection, stiffness, and stability are treated first.
Then fracture mechanics, failure criteria, fatigue phenomena, and surface damage of components are dealt with. These are followed by applications to the machine and miscellaneous mechanical and structural components.
All the sections attempt to provide an integrated approach that links together a variety of topics by means of case studies.
Some chapters and sections in the Mechanical Design of Machine Components by Ansel C.Ugural book are also carefully integrated through cross-referencing.
Throughout the Mechanical Design of Machine Components by Ansel C.Ugural book, most case studies provide numerous component projects.
They present different aspects of the same design or analysis problem in successive chapters. Case studies in the preliminary design of two machines are taken up in the last chapter.
Attention is given to the presentation of the fundamentals and necessary empirical information required to formulate design problems.
Important principles and applications are illustrated with numerical examples, and a broad range of practical problems are provided to be solved by students.
This Mechanical Design of Machine Components by Ansel C.Ugural book offers numerous worked-out examples and case studies, aspects of which are presented in several sections of the Mechanical Design of Machine Components by Ansel C.Ugural book; many problem sets, most of which are drawn from engineering practice; and a multitude of formulas and tabulations from which design calculations can be made.
Most problems can be readily modified for in-class tests. Answers to selected problems and References (identified in brackets) are given at the end of the Mechanical Design of Machine Components by Ansel C.Ugural book.
A sign convention consistent with vector mechanics is used throughout for loads, internal forces (with the exception of the shearin beams), and stresses.
This convention has been carefully chosen to conform to that used in most classical mechanics of materials, elasticity, and engineering design texts as well as to that most often employed in the numerical analysis of complex machines and structures.
Both the international system of units (SI) and the US customary system of units are used, but since in practice the former is replacing the latter, this Mechanical Design of Machine Components by Ansel C.Ugural book places a greater emphasis on SI units.
