Download or read book Thermomechanics of Composite Structures under High Temperatures written by Yu. I. Dimitrienko and published by Springer. This book was released on 2016-01-14 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This pioneering book presents new models for the thermomechanical behavior of composite materials and structures taking into account internal physico-chemical transformations such as thermodecomposition, sublimation and melting at high temperatures (up to 3000 K). It is of great importance for the design of new thermostable materials and for the investigation of reliability and fire safety of composite structures. It also supports the investigation of interaction of composites with laser irradiation and the design of heat-shield systems. Structural methods are presented for calculating the effective mechanical and thermal properties of matrices, fibres and unidirectional, reinforced by dispersed particles and textile composites, in terms of properties of their constituent phases. Useful calculation methods are developed for characteristics such as the rate of thermomechanical erosion of composites under high-speed flow and the heat deformation of composites with account of chemical shrinkage. The author expansively compares modeling results with experimental data, and readers will find unique experimental results on mechanical and thermal properties of composites under temperatures up to 3000 K. Chapters show how the behavior of composite shells under high temperatures is simulated by the finite-element method and so cylindrical and axisymmetric composite shells and composite plates are investigated under local high-temperature heating. The book will be of interest to researchers and to engineers designing composite structures, and invaluable to materials scientists developing advanced performance thermostable materials.

Book Synopsis High Temperature Performance of Polymer Composites by : Yu Bai
Download or read book High Temperature Performance of Polymer Composites written by Yu Bai and published by John Wiley & Sons. This book was released on 2014-03-31 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors explain the changes in the thermophysical and thermomechanical properties of polymer composites under elevated temperatures and fire conditions. Using microscale physical and chemical concepts they allow researchers to find reliable solutions to their engineering needs on the macroscale. In a unique combination of experimental results and quantitative models, a framework is developed to realistically predict the behavior of a variety of polymer composite materials over a wide range of thermal and mechanical loads. In addition, the authors treat extreme fire scenarios up to more than 1000?C for two hours, presenting heat-protection methods to improve the fire resistance of composite materials and full-scale structural members, and discuss their performance after fire exposure. Thanks to the microscopic approach, the developed models are valid for a variety of polymer composites and structural members, making this work applicable to a wide audience, including materials scientists, polymer chemists, engineering scientists in industry, civil engineers, mechanical engineers, and those working in the industry of civil infrastructure.

Book Synopsis Inelastic Analysis of Structures under Variable Loads by : Dieter Weichert
Download or read book Inelastic Analysis of Structures under Variable Loads written by Dieter Weichert and published by Springer Science & Business Media. This book was released on 2000-10-31 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question whether a structure or a machine component can carry the applied loads, and with which margin of safety, or whether it will become unserviceable due to collapse or excessive inelastic deformations, has always been a major concern for civil and mechanical engineers. The development of methods to answer this technologically crucial question without analysing the evolution of the system under varying loads, has a long tradition that can be traced back even to the times of emerging mechanical sciences in the early 17th century. However, the scientific foundations of the theories underlying these methods, nowadays frequently called "direct", were established sporadically in the Thirties of the 20th century and systematically and rigorously in the Fifties. Further motivations for the development of direct analysis techniques in applied mechanics of solids and structures arise from the circumstance that in many engineering situations the external actions fluctuate according to time histories not a priori known except for some essential features, e.g. variation intervals. In such situations the critical events (or "limit states") to consider, besides plastic collapse, are incremental collapse (or "ratchetting") and alternating plastic yielding, namely lack of "shakedown". Non evolutionary, direct methods for ultimate limit state analysis of structures subjected to variably-repeated external actions are the objectives of most papers collected in this book, which also contains a few contributions on related topics.

Book Synopsis Thermoforming of Thin-ply Composite Structures Via In-situ Heating by : Bojan Bijelic
Download or read book Thermoforming of Thin-ply Composite Structures Via In-situ Heating written by Bojan Bijelic and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates thermoforming of thin-ply thermoplastic composites via in-situ heating for in-space manufacturing applications. The proposed composite concept is based on combining conductive carbon nanotube (CNT) films and high-temperature thermoplastic matrix. The CNT film is made of randomly aligned carbon nanotubes, which possesses outstanding electrical, thermal, and mechanical properties. When combined with polymer matrix, it becomes a multifunctional composite structure. The thermoplastic chosen is polyether ether ketone (PEEK), which is a semicrystalline high-performance thermoplastic that has exceptional physical and mechanical properties at high temperatures. The composite structure studied is consists of a layer of CNT film sandwiched between two thin films of PEEK. The CNT acts as an in-situ conductive heater when a voltage difference is applied, and a mechanical reinforcement. The PEEK polymer impregnated with reinforcement fibers and CNT is capable of reforming by repeating the thermoforming process. The focus of this study is on developing and characterizing the manufacturing process suitable for in-space manufacturing, where CNT/PEEK can be treated as a composite prepreg capable of being reformed into different shapes on demand via thermoforming. The thermoforming of thin-ply composite structures is achieved solely via in-situ electrical heating.
Book Synopsis Isolation of Thermal and Strain Responses in Composites Using Embedded Fiber Bragg Grating Temperature Sensors by : Kyle Aspie Elam
Download or read book Isolation of Thermal and Strain Responses in Composites Using Embedded Fiber Bragg Grating Temperature Sensors written by Kyle Aspie Elam and published by . This book was released on 2013 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, fiber Bragg grating (FBG) optical temperature sensors are used for structural health monitoring of composite materials. The specific goal is to detect the thermal response of a composite to high energy radiation incident on the surface of a composite structure. FBG sensors also respond to axial strain in the optical fiber, thus any structural strain experienced by the composite is also detected. Consequently, this research has focused both on identifying the unique characteristics of each response and on developing feasible methods to isolate the thermal response from the strain response. Isolation ensures that any response to mechanical strain does not mask the response to a temperature gradient present on the composite surface. The isolation strategy developed in this research is characterized by two design features. First, a three-dimensional array of FBG temperature sensors has been embedded in a carbon/epoxy composite structure, consisting of both in-plane and through-thickness sensor arrays. This architectural design component exploits the spatial differences between the temperature profile and the strain profile in a composite structure. Second, an accompanying data processing scheme has been developed that uses the statistical properties of the collected sensor data to interpret and identify each response. The degree to which the isolation strategy increases the functionality of FBG temperature sensors in mechanically strained composite structures is assessed.
