Engineering Design: A Synthesis of Views
No full textDesign is a central activity in engineering. It is both a creative process not easily defined and a thought process that can, with increasing success, be externalized, articulated, and modeled. This book aims to clarify the issues, providing an operational definition of engineering design and an explication of design as a discipline. In particular, the book focuses on the contribution of AI (artificial intelligence) to engineering design. With its clear presentation of the main ideas of recent AI-based models of design, set within the context of inductive design models, the book offers an integrated view of current thinking about design. Also included is a brief review of some key AI-based problem-solving methods and classical design tools. The author closes with a look ahead at the roles that symbolic representation and knowledge-based (expert) systems can play in engineering design in practice and in education.https://scholarship.claremont.edu/hmc_facbooks/1019/thumbnail.jp
Principles of mathematical modeling
No full textScience and engineering students depend heavily on concepts of mathematical modeling. In an age where almost everything is done on a computer, author Clive Dym believes that students need to understand and "own" the underlying mathematics that computers are doing on their behalf. His goal for Principles of Mathematical Modeling, Second Edition, is to engage the student reader in developing a foundational understanding of the subject that will serve them well into their careers. The first half of the book begins with a clearly defined set of modeling principles, and then introduces a set of foundational tools including dimensional analysis, scaling techniques, and approximation and validation techniques. The second half demonstrates the latest applications for these tools to a broad variety of subjects, including exponential growth and decay in fields ranging from biology to economics, traffic flow, free and forced vibration of mechanical and other systems, and optimization problems in biology, structures, and social decision making. Prospective students should have already completed courses in elementary algebra, trigonometry, and first-year calculus and have some familiarity with differential equations and basic physics.* Serves as an introductory text on the development and application of mathematical models * Focuses on techniques of particular interest to engineers, scientists, and others who model continuous systems* Offers more than 360 problems, providing ample opportunities for practice * Covers a wide range of interdisciplinary topics--from engineering to economics to the sciences* Uses straightforward language and explanations that make modeling easy to understand and applyNew to this Edition:* A more systematic approach to mathematical modeling, outlining ten specific principles* Expanded and reorganized chapters that flow in an increasing level of complexity* Several new problems and updated applications* Expanded figure captions that provide more information* Improved accessibility and flexibility for teachin
Engineering design: a project based introduction
No full textIntroduces conceptual design methods and project management tools through description, example, and case study. Two design projects are consistently drawn upon to illustrate the design methods and management tools. Also covers important topic of reporting the results of a design project and provides useful insights into team behaviors and dynamics.* Enhanced coverage of communications and decision-making techniques.* Introduces conceptual design tools like objectives trees, morphological charts, and requirement matrices.* Covers project management tools, including work breakdown structures, Gantt charts, and project control toolshttps://scholarship.claremont.edu/hmc_facbooks/1026/thumbnail.jp
On Some Recent Approaches to Structural Optimization
No full textA tutorial survey of some recent approaches to structural optimization is given. Emphasis is placed on recent work which extends classical energy principles. Consideration is also given to the Pontryagin Maximum Principle and an application to structural problems. Consideration is given to both the static and dynamic behavior of structures
Consistent Derivations of Spring Rates for Helical Springs
No full textThe spring rates of a coiled helical spring under an axial force and an axially directed torque are derived by a consistent application of Castigliano’s second theorem, and it is shown that the coupling between the two loads may not always be neglected. The spring rate of an extensional spring is derived for the first time through the use of the displacement based principle of minimum total potential energy. The present results are also compared with available derivations of and expressions for the stiffness of a coiled spring
Stiffening of Bent Beams Due to Partial and Complete End Restraint
No full textA study of the effect of axial restraint on the bending deflections of centrally-loaded 3inned beams is presented. Exact and approximate solutions are given for the cases of no, partial, and full axial restraint. It is demonstrated that even moderate restraint can significantly increase the stiffness of the beam in response to transverse loading

Design and Design Centers in Engineering Education
Get PDFThis paper is intended to be the opening salvo of the workshop, Computing Futures in Engineering Design (Dym, 1997). Thus, I want to take this privileged moment to ask you to think with me about the role of design in engineering. In particular, I want to reflect upon how design is articulated and how design is taught; about the role of design in engineering education and in the practice of engineering; and about the role that could be played locally and, perhaps, nationally by a center devoted to design education. Because I teach here at Harvey Mudd College (HMC), and because most of you are visitors, I will place my remarks in our context by telling you about what we do here and how that doing has shaped my thinking
