This book was released on 1996 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was undertaken to evaluate the constitutive response and in-elastic deformation characteristics in titanium-based metal matrix composites (MMC) with two types of ceramic fibers, namely, SCS-6 and Sigma. The titanium matrix was Beta 21S, currently named TIMETAL-21S. Monotonic tests were conducted at room temperature (RT) and between 483 and 815°C. The inelastic deformation in the [0]8 lamina under compression was controlled primarily by matrix plasticity, although some evidence of fiber-matrix debonding was observed. The inelastic deformation mechanisms under compression in [90]8 lamina were primarily due to radial fiber cracking from the core for the SCS-6 fiber and fiber-matrix debonding. However, for the Sigma fiber, radial cracking was absent. The effect of temperature on degradation of mechanical properties such as modulus and yield strength for the composites with two different fibers were compared.

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.

Download or read book The Micromechanics of Deformation and Failure in Metal Matrix Composites written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals reinforced with ceramic fibers or particulates are promising materials for use in new generations of aerospace structures, propulsion devices and energy conversion systems. Furthermore, the controllability of many of these variables opens up the possibility of engineering materials for specific applications, if the effects of alterations in microstructure can be predicted. However, metal-matrix composites often have low ductility and low fracture toughness. An improved understanding of the basic deformation and failure mechanisms is needed to overcome these problems. To this end, research was carried out in three areas: (1) continuum modeling of deformation and fracture in metal-matrix composites, including the interaction between failure mechanisms using phenomenological constitutive relations to characterize each of the main failure modes in metal-matrix composites, reinforcement cracking, interfacial debonding and matrix void nucleation, growth and coalescence; (2) numerical studies of the propagation of fast cracks along and across interfaces, with a particular focus on understanding crack propagation from a brittle phase into a ductile phase; and (3) discrete dislocation modeling of matrix plastic deformation in metal-matrix composites with micron size reinforcements.

Download or read book Constitutive Modeling of Metal Matrix Composites Under Cyclic Loading written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A micro-mechanical cyclic/fatigue damage model is developed for metal matrix composites. The model is based on thermodynamical principles within the framework of continuum damage mechanics and employs physical principles of damage behavior in metal matrix composites. A micro-mechanical approach is used in the sense that the overall material behavior is predicted by modeling the material behavior of the individual constituents. The Mori-Tanaka method is employed as a homogenization procedure. Individual anisotropic damage variables in the form of second order tensors are used for each of the constituents to allow for the modeling of appropriate damage and failure mechanisms in the composite. Individual damage initiation and evolution equations are developed for each constituent where physical principles of the damage mechanisms observed in experiments are considered. Damage mechanisms such as debonding and delamination are represented through individual damage tensors. The overall damage in the composite is obtained based on the individual damage tensors by means of the employed homogenization procedure. The elasto-plastic constitutive equations incorporate the influence of damage through the definition of the so-called damage effect tensors. A numerical implementation of the model is used to simulate cyclic/fatigue damage in metal matrix composites. Comparison of the results from the numerical simulations with experimental data show good agreement and substantiate the capabilities of the model.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results of the analysis of the constitutive response of a model Metal Matrix Composite (MMC) system. The model is described first, followed by some direct comparison of predicted response to corresponding experimental data. An important result discussed here is that when model verification is made, it is important to compare load direction response to the experimental data, but also, comparisons to the out of load direction response must be made, or the model may not be performing as desired. Some discussion of failure predictions using simple models is also made here.

Available in PDF, EPUB and Kindle. Book excerpt: Polymer matrix composites are increasingly replacing traditional materials, such as metals, for applications in the aerospace, automotive and marine industries. Because of the relatively recent development of these composites there is extensive on-going research to improve the understanding and modelling of their behaviour – particularly their failure processes. As a consequence there is a strong demand among design engineers for the latest information on this behaviour in order to fully exploit the potential of these materials for a wide range of weight-sensitive applications. Failure mechanisms in polymer matrix composites explores the main types of composite failure and examines their implications in specific applications.Part one discusses various failure mechanisms, including a consideration of manufacturing defects and addressing a variety of loading forms such as impact and the implications for structural integrity. This part also reviews testing techniques and modelling methods for predicting potential failure in composites. Part two investigates the effects of polymer-matrix composite failure in a range of industries including aerospace, automotive and other transport, defence, marine and off-shore applications. Recycling issues and environmental factors affecting the use of composite materials are also considered.With its distinguished editors and international team of expert contributors Failure mechanisms in polymer matrix composites is a valuable reference for designers, scientists and research and development managers working in the increasing range of industries in which composite materials are extensively used. The book will also be a useful guide for academics studying in the composites field. Discusses various failure mechanisms, including manufacturing defects Reviews testing techniques and modelling methods for predicting potential failure Investigates failure in aerospace, automotive, defence, marine and off-shore applications

Download or read book Constitutive Modeling and Finite Element Analysis of Fatigue Damage in Metal Matrix Composites written by and published by . This book was released on 1996 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: A micromechanical consistent and systematic theory is developed for the analysis of damage mechanisms in metal matrix composites. A coupled incremental damage and plasticity theory of metal matrix composites is introduced here. This allows damage to be path dependent either on the stress history or the thermodynamic force conjugate to damage. This is achieved through the use of incremental damage tensors. The model involves both overall and local approaches to characterize damage in these material due to cyclic and monotonic loads. Expressions are derived here for the elasto-plastic stress and strain concentration tensors for fibrous metal matrix composite materials in the damaged configurations. A finite element analysis is used for quantifying each type of damage and predicting the failure loads of dog-bone shaped specimen and center-cracked laminate metal matrix composite plates. The development of damage zones and the stress-strain response are shown for two types of laminated layups.
