Feature-driven Method for Structural Optimization Design

Structural optimization is a method for achieving lightweight and high-performance engineering designs. Feature-based design, in turn, is the key method in state-of-the-art computer aided design (CAD). Both methods have developed independently, and are largely separate. The key problem that the separation of the two methods engenders, is that it is difficult to bring together mechanical performance design and feature requirements systematically. Feature-driven Method for Structural Optimization Design details a novel structural optimization method within a CAD framework, integrating structural optimization and feature-based design. It presents cutting-edge research on advanced structures. The title introduces a feature-driven structural optimization method, by regarding engineering features as basic design primitives. Consequently, it presents a method that allows structural optimization and feature design to be done at the same time, so that feature attributes are preserved throughout the design process. The book illustrates and supports the effectiveness of the method described, and shows potential applications, through presenting numerical modeling techniques and their programming. This volume presents a high-performance optimization method adapted to engineering structures-a novel perspective that will help engineers in the computation, modeling, and design of advanced structures. Integrates two independent methods - structural optimization, and feature-based design-into one frameworkAdapts the high performance optimization method to the practice of designing engineering structuresProvides numerical evidence for the effectiveness and potential of the methods describedWorks within a computer-aided design framework to develop a novel structural optimization methodologyPresents engineering features as the basic design primitives in structural optimization INDICE: 1.
