Multidisciplinary Design and Optimization of Aerospace Composite Materials is a collection of ten SAE technical papers focusing on the design analysis of aerospace composite structures from the perspective of various disciplines. The book concentrates on the following aspects: • Analytical methods for weight design of aircraft structures, including a parametric geometry model capable of generating dedicated models for both aerodynamic and structural solvers. • Methodologies for evaluating the structural performance of carbon/epoxy composite panels. • An aerodynamic design of flexible wings made of composite structures. • Thermal design and analysis of composite enclosures. • Methodologies for analyzing the acoustic performance of composite structures, including the design optimization method to evaluate the acoustic performance in terms of transmission loss (TL) of various composite panels. • The lightening effect on composites, presenting a theoretical method to compute the electrical current propagating through composite structures due to lightning strikes. • The issue of fire resistance as most polymer resins are flammable once the respective ignition temperatures are reached. • A probabilistic-based reliability analysis of the composite structures. The method is demonstrated on a graphite/epoxy composite space habitat subjected to the debris attacks. • A sustainability analysis of aircraft composite materials, including improved durability, less maintenance, and lower energy consumption.

Design and Analysis of Composite Structures enables graduate students and engineers to generate meaningful and robust designs of complex composite structures. Combining analysis and design methods for structural components, the book begins with simple topics such as skins and stiffeners and progresses through to entire components of fuselages and wings. Starting with basic mathematical derivation followed by simplifications used in real-world design, Design and Analysis of Composite Structures presents the level of accuracy and range of applicability of each method. Examples taken from actual applications are worked out in detail to show how the concepts are applied, solving the same design problem with different methods based on different drivers (e.g. cost or weight) to show how the final configuration changes as the requirements and approach change. Provides a toolkit of analysis and design methods to most situations encountered in practice, as well as analytical frameworks and the means to solving them for tackling less frequent problems. Presents solutions applicable to optimization schemes without having to run finite element models at each iteration, speeding up the design process and allowing examination of several more alternatives than traditional approaches. Includes guidelines showing how decisions based on manufacturing considerations affect weight and how weight optimization may adversely affect the cost. Accompanied by a website at www.wiley.com/go/kassapoglou hosting lecture slides and solutions to the exercises for instructors.

Based on course-tested material, this rigorous yet accessible graduate textbook covers both fundamental and advanced optimization theory and algorithms. It covers a wide range of numerical methods and topics, including both gradient-based and gradient-free algorithms, multidisciplinary design optimization, and uncertainty, with instruction on how to determine which algorithm should be used for a given application. It also provides an overview of models and how to prepare them for use with numerical optimization, including derivative computation. Over 400 high-quality visualizations and numerous examples facilitate understanding of the theory, and practical tips address common issues encountered in practical engineering design optimization and how to address them. Numerous end-of-chapter homework problems, progressing in difficulty, help put knowledge into practice. Accompanied online by a solutions manual for instructors and source code for problems, this is ideal for a one- or two-semester graduate course on optimization in aerospace, civil, mechanical, electrical, and chemical engineering departments.

Rapidly varying material and geometrical characteristics of composite materials and structures do not allow the direct study of their mechanical behavior even with the use of modern computers. This book is devoted to the mechanical design and optimization problems of composite structures, based on the previously developed asymptotic homogenization models and on the newly elaborated rigorous mathematical methods. It describes how to construct mathematically rigorous mechanical models to determine strength, stiffness, and weight minimization requirements, all important factors of design and optimization.

"This thesis contains three papers that focus on composites that pertain to a variety of structures commonly found in the aerospace industry. The first paper presents an investigation of the stowage and deployment strength of a thin carbon fiber-reinforced polymer shell capable of being rolled and stowed in a tight rolled configuration. The intent of this structure is for use as a segment of a larger deployable reflective aperture. This study involved finite element analysis of several laminates, coupon-level and full-scale prototype testing, which provided a much needed insight and benchmark of composite shells used in this manner. The second paper outlines the principles and mathematical backgrounds of functionally graded materials (FGM) in engineering, as well as a review of representative recent studies of such materials. Additionally contained in this paper is an example that demonstrates the advantages FGM structures can provide. This example involves the optimization of a sandwich plate with in-surface graded facings to increase the bucking load and fundamental frequency without any weight penalty. This study was performed by interfacing the commercial finite element code Abaqus, with the Sandia National Laboratories developed optimization toolkit DAKOTA. The third paper focuses on energy harvesting using a flextensional bimorph. In this paper, a new concept of utilizing piezoelectric bimorph harvesters in combination with a flextensional strain amplifier is featured. To demonstrate the energy harvesting capabilities using this concept, a nonlinear finite element analysis of the bimorph harvester was conducted. As follows from the analysis, the new concept offers a possibility to harvest energy in a broad spectrum of driving frequencies, eliminating the major weakness of standard bimorphs related to a narrow useful frequency range. The papers contained in this thesis have displayed significant advancements to their respective application. The concepts and solutions considered in the papers offer significant possibilities for a development of advance aerospace structures"--Abstract, leaf iv.

Since the successful production of carbon fibers in early 1960s, composite materials have emerged as the materials of choice for general aviation aircraft, military aircraft, space launch vehicles, and unmanned air vehicles. This has revolutionized the aerospace industry due to their excellent mechanical and physical properties, as well as weight-reducing ability. The next- generation material development model should operate in an integrated computational environment, where new material development, manufacturability, and product design practice are seamlessly interconnected. Materials and Process Modeling of Aerospace Composites reports recent developments on materials and processes of aerospace composites by using computational modeling, covering the following aspects: • The historical uses of composites in aerospace industry, documenting in detail the early usage of composite materials on Premier I by Raytheon to recent full-scale applications of composites on large commercial aircraft by Boeing and Airbus. • An overview on the classifications of composites used in aerospace industry, ranging from conventional glass- fiber reinforced composites to advanced graphene nanocomposites. • The recent work on computational material engineering on aerospace composite materials, including fundamental computational frame work and case studies on the modeling of materials and processes
