This book attempts to develop an integrative method that combines the processing and mechanical simulations for z-pinned carbon fiber-reinforced polymer (CFRP) composites. The topics in this book cover experimental characterization, processing modeling, mechanical simulation, and the integrated analysis method for z-pinned CFRP composites. Explanations are made in detail about how to combine the processing induced residual stress and z-pin/composite interfacial debonding with tensile strength, failure mode, and bridging tractions modeling and simulations for z-pinned CFRP composites. This book is considered as a complementary work of existing books about composites mechanics and processing. This book is used as a guideline for graduate students and research engineers who wish to learn the basic modeling techniques in processing and characterizing z-pinned CFRP composites. For reading the book, readers will need the technical background of mechanics and finite element method.

The Feature-Driven Method for Structural Optimization details a novel structural optimization method within a CAD framework, integrating structural optimization and feature-based design. The book presents cutting-edge research on advanced structures and introduces the 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 simultaneously so that feature attributes are preserved throughout the design process. The book illustrates and supports the effectiveness of the method described, showing potential applications through numerical modeling techniques and 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.

Mechanical Properties of Polycarbonate: Experiment and Modeling for Aeronautical and Aerospace Applications provides a detailed description on experimental characterization, material modeling and finite element simulation method for polycarbonate in aeronautical and aerospace applications. The book presents the experiment facilities and methods used in characterizing the mechanical properties of polycarbonate in a large range of strain rates and temperatures. The constitutive modeling of polycarbonate and the finite element simulation of polycarbonate products under impact loading are illustrated in detail. Finally, an optimization methodology is devised to optimize the injection molding process parameters for high mechanical performance of the product under impact loading.

Reliable scheduling in cutting conditions is very important in machining processes, and this requires thorough understanding of the physical behaviors of the machining process, which cannot be achieved without understanding the underlying mechanism of the processes. The book describes the mechanics and dynamics together with the clamping principles in milling processes, and can be used as a guideline for graduate students and research engineers who wish to be effective manufacture engineers and researchers. Many books have focused on common principles, which are suitable for general machining processes, e.g., milling, turning and drilling, etc. This book specifically aims at exploring the mechanics and dynamics of milling processes. Original theoretical derivations and new observations on static cutting force models, dynamic stability models and clamping principles associated with milling processes are classified and detailed. The book is indented as a text for graduate students and machining engineers who wish to intensively learn milling mechanism and machine tool vibration.
