Available in PDF, EPUB and Kindle. Book excerpt: This book contains fifteen papers based on the presentations made at the symposium on "Inelasticity and Micromechanics of Metal Matrix Composites" held at the University of Washington, USA, in mid-1994. The papers represent the most recent work conducted on inelasticity and micromechanics of metal matrix composites. The book is divided into two parts: Part I deals with the study of inelastic deformation in metal matrix composites, while Part II tackles the micromechanical aspects of metal matrix composites. The articles discuss different aspects of these two topics ranging from purely theoretical treatments to extensive experimental investigations. Many of the papers are by prominent researchers working in this area.

This book was released on 2018-10-21 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A macro-micromechanics analysis was formulated to determine the matrix and fiber behavior near the notch tip in a center-notched metal matrix composite. Results are presented for a boron/aluminum monolayer. The macro-level analysis models the entire notched specimen using a three dimensional finite element program which uses the vanishing-fiber-diameter model to model the elastic-plastic behavior of the matrix and the elastic behavior of the fiber. The micro-behavior is analyzed using a Discrete Fiber-Matrix (DFM) model containing one fabric and the surrounding matrix. The dimensions of the DFM model were determined by the ply thickness and the fiber volume fraction and corresponded to the size of the notch-tip element in the macro-level analysis. The boundary conditions applied to the DFM model were determined from the macro-level analysis. Stress components within the DFM model were calculated and stress distributions are presented along selected planes and surfaces within the DFM model, including the fiber-matrix interface. Yielding in the matrix was examined at the notch tip in both the macro- and micro-level analyses. The DFM model predicted higher stresses (24 percent) in the fiber compared to the global analysis. In the notch-tip element, the interface stresses indicated that a multi-axial criterion may be required to predict interfacial failure. The DFM analysis predicted yielding to initiate in the notch-tip element at a stress level 28 percent lower than predicted by the global analysis. Bigelow, C. A. and Naik, R. A.

Available in PDF, EPUB and Kindle. Book excerpt: A macro-micromechanics analysis was formulated to determine the matrix and fiber behavior near the notch tip in a center-notched metal matrix composite. Results are presented for a boron/aluminum monolayer. The macro-level (or global) analysis models the entire notched specimen using a three-dimensional finite element program that uses the vanishing-fiber-diameter model to model the elastic-plastic behavior of the matrix and the elastic behavior of the fiber. The micro-behavior is analyzed using a discrete fiber-matrix (DFM) model containing one fiber and the surrounding matrix. The dimensions of the DFM model were determined by the ply thickness and the fiber volume fraction and corresponded to the size of the notch-tip element in the macro-level analysis. The boundary conditions applied to the DFM model were determined from the macro-level analysis. Stress components within the DFM model were calculated, and stress distributions are presented along selected planes and surfaces within the DFM model, including the fiber-matrix interface. Yielding in the matrix was examined at the notch tip in both the macro- and micro-level analyses. The DFM model predicted higher stresses (24%) in the fiber than predicted by the global analysis. In the notch-tip element, the interface stresses indicated that a multi-axial stress criterion may be required to predict interfacial failure.

Download or read book Advances in Damage Mechanics Metals and Metal Matrix Composites written by George Voyiadjis and published by Elsevier. This book was released on 2012-12-02 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in a single and unified volume a clear and thorough presentation of the recent advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory. In addition, some sections contain new material that has not appeared before in the literature. The book is divided into three major parts: Part I deals with the scalar formulation and is limited to the analysis of isotropic damage in materials; Parts II and III deal with the tensor formulation and is applied to general states of deformation and damage. The material appearing in this text is limited to plastic deformation and damage in ductile materials (e.g. metals and metal matrix composites) but excludes many of the recent advances made in creep, brittle fracture, and temperature effects since the authors feel that these topics require a separate volume for this presentation. Furthermore, the applications presented in this book are the simplest possible ones and are mainly based on the uniaxial tension test.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers several aspects of the synthesis of composites by the pressureless infiltration technique. It describes the methods used to obtain green preforms, such as cold pressed and hot sintering, describing the heating time, load, and time required for pressing the preforms. Additionally, wettability phenomena, which is directly related on infiltration, is extensively described. Wettability process and interfacial reactions are analyzed in many ceramic-metal systems prior to fabricate the composites. A complete description of fabrication processes for Metal Matrix Composites is included. An extensive section on structural, chemical, and mechanical characterization of composites fabricated with aluminum and magnesium alloys as matrices reinforced with titanium carbide (TiC), aluminum nitride (AlN), silicon carbide (SiC) and alumina (Al2O3) is included. Relevant techniques for joining composites, such as welding and brazing are addressed. As well as issues pertaining to the corrosion and wear of composites are discussed as well. Corrosion behavior of some composites exposed to aqueous media was analyzed. Corrosion of composites using TiC and SiC like reinforcement and Al, Ni, and some Al-Cux, Al-Mgx and Al-Cu-Li alloys like matrix is discussed extensively. The structural characterization techniques addressed include: scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), optical microscopy (OM), differential thermal analysis (DTA), high resolution transmission electron microscopy (HRTEM), and thermogravimetry analysis (TGA). Mechanical testing including hardness, elastic modulus, tension tests, and impact tests were used in the characterization of composites. Theoretical models for prediction of some mechanical properties are included too.
