Efficient Branch and Bound Search with Application to Computer-Aided Design describes an efficient branch-and-bound method for logic justification, which is fundamental to automatic test pattern generation (ATPG), redundancy identification, logic synthesis, minimization, verification, and other problems in CAD. The method is called justification equivalence, based on the observation that justification processes may share identical subsequent search decision sequences. With justification equivalence, duplication of computations is avoided in the dynamic branch-and-bound search process without using search decision trees.

MACHINE DESIGN WITH CAD AND OPTIMIZATION A guide to the new CAD and optimization tools and skills to generate real design synthesis of machine elements and systems Machine Design with CAD and Optimization offers the basic tools to design or synthesize machine elements and assembly of prospective elements in systems or products. It contains the necessary knowledge base, computer aided design, and optimization tools to define appropriate geometry and material selection of machine elements. A comprehensive text for each element includes: a chart, excel sheet, a MATLAB® program, or an interactive program to calculate the element geometry to guide in the selection of the appropriate material. The book contains an introduction to machine design and includes several design factors for consideration. It also offers information on the traditional rigorous design of machine elements. In addition, the author reviews the real design synthesis approach and offers material about stresses and material failure due to applied loading during intended performance. This comprehensive resource also contains an introduction to computer aided design and optimization. This important book: Provides the tools to perform a new direct design synthesis rather than design by a process of repeated analysis Contains a guide to knowledge-based design using CAD tools, software, and optimum component design for the new direct design synthesis of machine elements Allows for the initial suitable design synthesis in a very short time Delivers information on the utility of CAD and Optimization Accompanied by an online companion site including presentation files Written for students of engineering design, mechanical engineering, and automotive design. Machine Design with CAD and Optimization contains the new CAD and Optimization tools and defines the skills needed to generate real design synthesis of machine elements and systems on solid ground for better products and systems.

This book summarizes advances in a number of fundamental areas of optimization with application in engineering design. The selection of the 'best' or 'optimum' design has long been a major concern of designers and in recent years interest has grown in applying mathematical optimization techniques to design of large engineering and industrial systems, and in using the computer-aided design packages with optimization capabilities which are now available.

Optimierungsgestütztes Entwerfen und Bemessen liefert neuartige Methoden, bewehrten Beton besonders effizient einzusetzen. Dabei wird die mathematische Optimierung auf die praktischen Probleme des Betonbaus angewendet. Ziel ist es, sparsam mit dem weltweit meistverwandten Baustoff Stahlbeton umzugehen und damit den CO2-Ausstoß aus der Zement- und Stahlherstellung und den Ressourcenverbrauch an Kies, Sand und Wasser substanziell zu reduzieren. Drei Themenbereiche sind angesprochen. Erstens, die Strukturfindung, also die Frage nach der richtigen äußeren Form, dass schlanke, nach dem Kraftfluss ausgerichtete Tragwerke entstehen. Baustoffgerecht sind sie weitgehend auf Druck beansprucht. Zweitens, die Bewehrungsführung, die sich am inneren Kraftfluss orientiert. Vorteile ergeben sich gerade für Scheiben, volumenartige Bauteile, an Lasteinleitungsbereichen und Aussparungen. Es entstehen anschauliche, direkt in Bewehrungen umsetzbare Fachwerkmodelle. Dritter Entwicklungsschritt ist die Behandlung von Querschnitten. Sie werden in ihrer Form optimiert und in ihrer Bewehrung bemessen. Dies gilt auch für anspruchsvolle Beanspruchungen (zweiachsige Biegung) und nahezu beliebige Formen. Eine Parametrisierung ermöglicht die allgemeingültige Übertragung auf ganze Klassen von Querschnitten. Die optimierungsgestützten Methoden werden vertieft und anschaulich beschrieben. Sie sind universell anwendbar und unabhängig von Normen, Betonarten und Bewehrungen. Sie gelten für normalfeste bis zu ultrahochfesten Betonen, für Bewehrungen aus Stahl, Carbon oder Glasfasern und für Bewehrungsstäbe als auch -fasern. Zahlreiche Abbildungen und Berechnungsbeispiele verdeutlichen die Anwendung. Zudem werden praktische Umsetzungen vorgestellt, darunter ultra-leichte Stahl-Beton-Balken, schlanke Solarkollektoren aus Beton und verbesserte Bewehrungslayouts für Tunnelschalen. Das Buch richtet sich gleichermaßen an Studierende, Forscher und Praktiker.

4 lation and optimization. These are essential constituents of the iterative process, leading to a feasible and, one hopes, optimal design. 1.3 Content of the Book In Chapter 2 we present briefly the history of CAD. The main components of CAD systems are identified, and their principal functions described. Economi cal and interdisciplinary aspects are discussed. Chapter 3 starts with a systems analysis of the design process. The notion of a process is introduced as a fundamental tool to describe activities like design as a whole, computer-aided design, program executions, terminal sessions etc. The environment and the resources which the environment must supply for the successful execution of any process are discussed. The problem of modelling the design objects in an abstract schema and the interrelation between the schema and the planning of the individual step in the design are analysed. Chapter 4 concentrates on the interfaces among the components of a CAD system, including the human operator. The problem of mapping an abstract schema onto the capabilities of various programming, command, or data de scription languages is described in detail. Emphasis is laid upon the resource aspect and its influence on the design of CAD systems. The concept of a CAD software machine is introduced, and rules for designing such machines are given.

Broad coverage of digital product creation, from design to manufacture and process optimization This book addresses the need to provide up-to-date coverage of current CAD/CAM usage and implementation. It covers, in one source, the entire design-to-manufacture process, reflecting the industry trend to further integrate CAD and CAM into a single, unified process. It also updates the computer aided design theory and methods in modern manufacturing systems and examines the most advanced computer-aided tools used in digital manufacturing. Computer Aided Design and Manufacturing consists of three parts. The first part on Computer Aided Design (CAD) offers the chapters on Geometric Modelling; Knowledge Based Engineering; Platforming Technology; Reverse Engineering; and Motion Simulation. The second part on Computer Aided Manufacturing (CAM) covers Group Technology and Cellular Manufacturing; Computer Aided Fixture Design; Computer Aided Manufacturing; Simulation of Manufacturing Processes; and Computer Aided Design of Tools, Dies and Molds (TDM). The final part includes the chapters on Digital Manufacturing; Additive Manufacturing; and Design for Sustainability. The book is also featured for being uniquely structured to classify and align engineering disciplines and computer aided technologies from the perspective of the design needs in whole product life cycles, utilizing a comprehensive Solidworks package (add-ins, toolbox, and library) to showcase the most critical functionalities of modern computer aided tools, and presenting real-world design projects and case studies so that readers can gain CAD and CAM problem-solving skills upon the CAD/CAM theory. Computer Aided Design and Manufacturing is an ideal textbook for undergraduate and graduate students in mechanical engineering, manufacturing engineering, and industrial engineering. It can also be used as a technical reference for researchers and engineers in mechanical and manufacturing engineering or computer-aided technologies.
