This book was released on 1990 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A parametric study was conducted to assess the effect of thermal residual stresses on the stress-strain response of a fiber-reinforced metal-matrix composite. The material chosen for investigation was silicon carbides/whisker reinforced Al 6061 system. The effects of fiber volume fraction, fiber aspect ratio and fiber spacing were analyzed within the framework of axisymmetric finite element models to determine the overall constitutive response of the composite materials as well as to solve for local field quantities in the fiber and matrix. The composite was modeled as a periodic array of cylindrical fibers, laterally aligned in one model and staggered in the other. Perfect interfacial bonding and complete fiber alignment with the tensile axis were assumed. The results indicated that (1) composite stiffness, yield strength and work hardening rate increased with increasing volume fraction and fiber aspect ratio and (2) variations in fiber spacing primarily affect work hardening rate and have negligible effect on composite stiffness. It was found that the presence of residual stresses affected the stress-strain behavior of the composite by influencing the load transfer characteristics between the matrix and fiber as well as the initiation and growth of plastic deformation in the matrix.

This book was released on 1991 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: A phenomenological and parametric study was conducted to assess the effect of thermal residual stresses on the stress-strain response of a discontinuous fiber-reinforced metal-matrix composite in tensile and compressive loading. The material chosen for this investigation was the silicon carbide whisker reinforced aluminum 6061. The difference between composite flow behavior in tension and compression, as well as the effects of volume fraction, fiber aspect ratio and fiber spacing were analyzed within the framework of axisymmetric finite element models to determine the overall constitutive response of the composite and to solve for local field quantities in the fiber and the matrix. The composite was modeled as a periodic array of cylindrical fibers with perfect interfacial bonding and complete fiber alignment with the tensile/compressive axis. It was found that the presence of residual stresses affected the stress-strain behavior of the composite by influencing the load transfer characteristics between the matrix and the fiber as well as the initiation and growth of the plastic deformation in the matrix. The results of the study indicated that a significant strength differential exists between tensile and compressive loading and that this effect diminishes with increasing volume fraction. The results also indicated that composite stiffness, yield strength and work-hardening rate increase with increasing volume fraction and fiber aspect ratio.

Download or read book Residual Stresses in Composite Materials written by Mahmood M. Shokrieh and published by Woodhead Publishing. This book was released on 2014-02-14 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly.The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed.Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries. - Reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses - Discusses residual stresses in polymer matrix, metal-matrix and other types of composite - Considers the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses
Book Synopsis The Effect of Thermal Residual Stresses on the Asymmetric Constitutive Behavior of Metal-Matrix Composites by : N. Shi
Download or read book The Effect of Thermal Residual Stresses on the Asymmetric Constitutive Behavior of Metal-Matrix Composites written by N. Shi and published by . This book was released on 1991 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical investigation of the difference in the constitutive behavior of silicon carbide-aluminum (SiC-Al) composites under uniaxial compressive and tensile loading was carried out, and the associated changes of the residual stresses were studied. It is suggested that the observed asymmetric response of the constitutive behavior is primarily due to the existence of residual stresses in the composite. These residual stresses are initially introduced because of the differences in the coefficients of thermal expansion (?CTE) during the cooling process and subsequently changed after the external load is applied. A two-dimensional (2-D) finite element analysis of a hexagonal array of SiC whiskers in an Al matrix was performed, the result of which testifies to the appropriateness of the proposed explanation. It is concluded that the 2-D finite element analysis is an economical way of adequately reproducing the most prominent features of the material's constitutive behavior. Based upon the theory of mechanics of composite material, simplified analytical models were developed which can be used to investigate the influences of the whisker-matrix interface shear load transfer and the volume mismatch on the residual stresses. It is concluded that the mechanism of load transfer in terms of normal stress at the whisker tip, which is governed by the volume (bulk) mismatch between the matrix and the whisker, is predominantly responsible for altering the specific pattern of the residual stresses under the applied load. In contrast, the effect of shear load transfer at the longitudinal whisker-matrix interface is only restricted to a very small region in the vicinity of the whisker and does not influence the overall symmetry of the constitutive behavior.

Book Synopsis Stress Analysis of Fiber-reinforced Composite Materials by : M. W. Hyer
Download or read book Stress Analysis of Fiber-reinforced Composite Materials written by M. W. Hyer and published by DEStech Publications, Inc. This book was released on 2009 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updated and improved, Stress Analysis of Fiber-Reinforced Composite Materials, Hyer's work remains the definitive introduction to the use of mechanics to understand stresses in composites caused by deformations, loading, and temperature changes. In contrast to a materials science approach, Hyer emphasizes the micromechanics of stress and deformation for composite material analysis. The book provides invaluable analytic tools for students and engineers seeking to understand composite properties and failure limits. A key feature is a series of analytic problems continuing throughout the text, starting from relatively simple problems, which are built up step-by-step with accompanying calculations. The problem series uses the same material properties, so the impact of the elastic and thermal expansion properties for a single-layer of FR material on the stress, strains, elastic properties, thermal expansion and failure stress of cross-ply and angle-ply symmetric and unsymmetric laminates can be evaluated. The book shows how thermally induced stresses and strains due to curing, add to or subtract from those due to applied loads.Another important element, and one unique to this book, is an emphasis on the difference between specifying the applied loads, i.e., force and moment results, often the case in practice, versus specifying strains and curvatures and determining the subsequent stresses and force and moment results. This represents a fundamental distinction in solid mechanics.

Book Synopsis Thermal Stress Effects in Intermetallic Matrix Composites by : National Aeronautics and Space Administration (NASA)
Download or read book Thermal Stress Effects in Intermetallic Matrix Composites written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-23 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermetallic matrix composites develop residual stresses from the large thermal expansion mismatch (delta-alpha) between the fibers and matrix. This work was undertaken to: establish improved techniques to measure these thermal stresses in IMC's; determine residual stresses in a variety of IMC systems by experiments and modeling; and, determine the effect of residual stresses on selected mechanical properties of an IMC. X ray diffraction (XRD), neutron diffraction (ND), synchrotron XRD (SXRD), and ultrasonics (US) techniques for measuring thermal stresses in IMC were examined and ND was selected as the most promising technique. ND was demonstrated on a variety of IMC systems encompassing Ti- and Ni-base matrices, SiC, W, and Al2O3 fibers, and different fiber fractions (Vf). Experimental results on these systems agreed with predictions of a concentric cylinder model. In SiC/Ti-base systems, little yielding was found and stresses were controlled primarily by delta-alpha and Vf. In Ni-base matrix systems, yield strength of the matrix and Vf controlled stress levels. The longitudinal residual stresses in SCS-6/Ti-24Al-llNb composite were modified by thermomechanical processing. Increasing residual stress decreased ultimate tensile strength in agreement with model predictions. Fiber pushout strength showed an unexpected inverse correlation with residual stress. In-plane shear yield strength showed no dependence on residual stress. Higher levels of residual tension led to higher fatigue crack growth rates, as suggested by matrix mean stress effects.
