Available in PDF, EPUB and Kindle. Book excerpt: Minimum weight design of aerospace structres has evolved during the past two decades into a rather rigorous scientific discipline that permits the rational selection of structural configurations and materials for various design requirements. Because of the pertinence of this body of literature to the structural design of advanced aerospace vehicles, a comprehensive bibliography of published literature on optimim structural design has been compiled and reviewed herein. In Part 1, a critical historical review highlights the significant advances in the literature concerned with analytical optimum design techniques for various structural elements, materials and thermal protection systems. The annotated bibliography is contained in Part 2. In Part 3, the current state of the art of the theory of optimum structural and thermostructural design is assessed. Included are the derivation of design indices resulting from various design requirements, a generalized presentation of optimum design theory and preferred methods of presenting optimum design results.

Book Synopsis Optimization in Structural Design by : A. Sawczuk
Download or read book Optimization in Structural Design written by A. Sawczuk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural optimization, a broad interdisciplinary field, requires skillful combining of mathematical and mechanical knowledge with engineering. It is both intellectually attractive and technologically rewarding. The Symposium on Optimization in Structural Design was the second IUTAM Symposium in Poland. Fifteen years have elapsed since the Symposium on Nonhomogeneity in Elasticity and Plasticity, presided by Professor Olszak, was held in Warsaw. These fifteen years mean a lot for mechanics in Poland. Continuing the tradition of Professor Maksymilian Tytus Huber's research, considerable development of the mechanical sciences has been achieved in this country mostly due to the knowledge, vision and persistence of Professors Wit old Nowacki and Waclaw Olszak, eminent Members of our Academy. The Institute of Fundamental Technological Research was established, competent research groups grew, matured and contri buted to thermo-elasticity, plasticity, general theory of constitutive equations, and to structural mechanics-just to mention a few do mains. Mechanics is now penetrating into the technology of this country at an accelerating pace. The optimization in mechanics has a tradition in Poland. In 1936 Professor Zbigniew Wasiutynski formulated the optimality criterion for mean stiffness design using an elastic energy concept. Further work in this field has been done since, mostly in the last ten years. On behalf of the Committee for Mechanics of the Polish Academy of Sciences I wish to thank the IUTA1V[ Bureau for the decision to hold in Warsaw the Symposium the present volume contains the contribu tions to.

Book Synopsis Criteria and Methods of Structural Optimization by : Andrzej M Brandt
Download or read book Criteria and Methods of Structural Optimization written by Andrzej M Brandt and published by Springer Science & Business Media. This book was released on 1987-06-30 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to serve all those who are interested in structural opti mization, whether they work in this field or study it for other purposes. Rapid growth of interest in the cognitive aspects of optimization and the increas ing demands that the present day engineer has to meet in modern design have created the need of a monographic treatment of the subject. The vast number and wide range of structural optimization problems formulated and investigated in the last twenty years call for an attempt to sum up the pres ent state of knowledge in this domain and to outline the directions of its further development. The present authors undertook this task, hoping that the result would stimulate further work towards finding new methods and solutions and increasing the range of applications of the optimization methods to structural design. The immediate aim of the book is to present the basic criteria and methods of optimization and to provide a reference guide to the most important publications in the field. 'The book consists of fourteen chapters. Chapter 1 introduces the basic concepts, definitions and assumptions relating to structural optimization. Chapter 2 gives the foundations of optimization for minimum elastic strain potential or maximum rigidity, and sets a basis for optimization of bar, plate and lattice structures. Chapter 3 presents criteria of strength design and their applications to plane structures.

Book Synopsis Approximate Multiple Configuration Analysis and Allocation for Least Weight Structural Design by : Robert J. Melosh
Download or read book Approximate Multiple Configuration Analysis and Allocation for Least Weight Structural Design written by Robert J. Melosh and published by . This book was released on 1967 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a rapid reanalysis technique (reducing analysis costs by factors between 2 and 100) and a rapid search procedure (reducing the number of design steps by a factor of 25) for obtaining optimum designs. Reanalysis is an approximate procedure based on extremum energy principles and leading, monotonically, to results as exact as desired. THe desing process is an allocation procedure. Each element of the structure is sized in turn. Optimization is addressed toward least weight design of truss systems with multiple loadings and a discrete set of admissible sizings (materials). The new technique can easily include prestress as a design variable. It can be extended to treat any set of finite elements and is based on use of the force or displacement method or both. Because of the modularity of calculations, it is well suited to computer implementation for multi-element structural systems.

Book Synopsis Structural Efficiencies of Five Compression Panels with Curved Elements by : Gary L. Giles
Download or read book Structural Efficiencies of Five Compression Panels with Curved Elements written by Gary L. Giles and published by . This book was released on 1971 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural-efficiency analyses are used to determine the minimum-mass proportions of some panel configurations loaded in uniaxial compression. Five panel constructions, four of which incorporate circular-arc elements and the other a beaded-web corrugation, are shown to have improved structural efficiencies over conventional configurations. In addition to the structural-efficiency equations, which give the mass equivalent flat-plate thickness of the panel necessary to carry a given load, related design equations for calculating the cross-sectional dimensions of these minimum-mass panels are presented. The upper and lower limits of loading, where the design constraints of minimum gage or material yield strength become the dominant design conditions, are established and the corresponding design equations which are applicable outside these limits are also presented.

Download or read book Panel Optimization with Integrated Software (POIS).: PANDA written by and published by . This book was released on 1981 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis and an interactive computer program are described through which minimum weight designs of composite, stiffened, cylindrical panels can be obtained subject to general and local buckling constraints and stress and strain constraints. The panels are subjected to arbitrary combinations of in-plane axial, circumferential, and shear resultants. Nonlinear material effects are included if the material is isotropic or has stiffness in only one direction (as does a discrete or a smeared stiffener). Several types of general and local buckling modes are included as constraints in the optimization process, including general instability, panel instability with either stringers or rings smeared out, local skin buckling, local crippling of stiffener segments, and general, panel, and local skin buckling including the effects of stiffener rolling. Certain stiffener rolling modes in which the panel skin does not deform but the cross section of the stiffener does deform are also accounted for. The interactive PANDA system consists of three independently executed modules that share the same data base. In the first module an initial design concept with rough (not necessarily feasible or accurate) dimensions are provided by the user in a conversational mode. In the second module the user decides which of the design parameters of the concept are to be treated by PANDA as decision variables in the optimization phase. In the third module the optimization calculations are carried out. Many examples are provided in which optimum designs obtained by PANDA are compared to those in the literature. (Author).
