Book Thermomechanical Cyclic Deformation of Metal Matrix Composites

Download or read book Thermomechanical Cyclic Deformation of Metal Matrix Composites written by M. Karayaka and published by . This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A constitutive model is developed for unreinforced Al2xxx-T4 and silicon-carbide particulate (SiCp) reinforced Al2xxx-T4. Its capabilities are also outlined for predicting the cyclic, isothermal, and thermomechanical behaviors of the composite and its constituents. The constitutive model for unreinforced Al2xxx-T4 is also a unified model, because it combines creep and plastic strains as inelastic strains. The unified model for the matrix is combined with Eshelby's equivalent inclusion theory, which is modified to handle finite volume fraction and inelastic deformation, to simulate the behavior of the reinforced material. The behavior of Al2xxx-T4 (reinforced with 20% volume fraction of SiCp) was simulated at temperatures ranging from 20 to 300°C and strain rates of 3.10-5 1/s to 3.10-3 1/s. The model predicts the strengthening of the composite relative to the unreinforced matrix for isothermal and thermomechanical loading conditions.

Book Metal Matrix Composites

Download or read book Metal Matrix Composites written by Minoru Taya and published by Elsevier. This book was released on 2016-01-11 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.

Book Fatigue under Thermal and Mechanical Loading Mechanisms Mechanics and Modelling

Download or read book Fatigue under Thermal and Mechanical Loading Mechanisms Mechanics and Modelling written by J. Bressers and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.

Book Analysis of Thermomechanical Cyclic Behavior of Unidirectional Metal Matrix Composites

Download or read book Analysis of Thermomechanical Cyclic Behavior of Unidirectional Metal Matrix Composites written by NE. Ashbaugh and published by . This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical tool is developed to determine the three-dimensional stress state in a unidirectional composite subjected to axial loading and changes in temperature. A finite difference method is used to analyze a representative volume element of the composite which consists of concentric cylinders. The constituents are assumed to be elastic-plastic materials having temperature dependent properties. An iterative technique using the Prandtl-Reuss flow rule to determine incremental plastic strains is implemented in a computer code capable of predicting the axisymmetric triaxial stresses in a composite under thermomechanical fatigue (TMF) loading conditions. The model is verified with finite element method calculations for the problem of thermal residual stresses resulting from cool-down from the processing temperature. Results for several TMF loading conditions are compared with experimental data and 1-D predictions for a SCS-6 silicon carbide fiber and Ti-24Al-11Nb matrix composite. Significant differences are noted between results based on 1-D and 3-D approximations to the stress state in a composite and are discussed in detail.

Book Combined Thermal and Bending Fatigue of High Temperature Metal Matrix Composites

Download or read book Combined Thermal and Bending Fatigue of High Temperature Metal Matrix Composites written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-30 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nonlinear behavior of a high-temperature metal-matrix composite (HT-MMC) was simulated by using the metal matrix composite analyzer (METCAN) computer code. The simulation started with the fabrication process, proceeded to thermomechanical cyclic loading, and ended with the application of a monotonic load. Classical laminate theory and composite micromechanics and macromechanics are used in METCAN, along with a multifactor interaction model for the constituents behavior. The simulation of the stress-strain behavior from the macromechanical and the micromechanical points of view, as well as the initiation and final failure of the constituents and the plies in the composite, were examined in detail. It was shown that, when the fibers and the matrix were perfectly bonded, the fracture started in the matrix and then propagated with increasing load to the fibers. After the fibers fractured, the composite lost its capacity to carry additional load and fractured. Gotsis, Pascal K. Glenn Research Center RTOP 510-10-01...
