Book Synopsis Brittle Fracture and Damage of Brittle Materials and Composites by : Jacques Lamon
Download or read book Brittle Fracture and Damage of Brittle Materials and Composites written by Jacques Lamon and published by Elsevier. This book was released on 2016-03-16 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flaws are the principal source of fracture in many materials, whether brittle or ductile, whether nearly homogeneous or composite. They are introduced during either fabrication or surface preparation or during exposure to aggressive environments (e. g. oxidation, shocks). The critical flaws act as stress concentrators and initiate cracks that propagate instantaneously to failure in the absence of crack arrest phenomena as encountered in brittle materials. This book explores those brittle materials susceptible to crack arrest and the flaws which initiate crack induced damage. A detailed description of microstructural features covering numerous brittle materials, including ceramics, glass, concrete, metals, polymers and ceramic fibers to help you develop your knowledge of material fracture. Brittle Failure and Damage of Brittle Materials and Composites outlines the technological progress in this field and the need for reliable systems with high performances to help you advance the development of new structural materials, creating advantages of low density, high resistance to elevated temperatures and aggressive environments, and good mechanical properties. The effects of flaw populations on fracture strength The main statistical-probabilistic approaches to brittle fracture The use of these methods for predictions of failure and effects induced by flaw populations The application of these methods to component design The methods of estimation of statistical parameters that define flaw strength distributions The extension of these approaches to damage and failure of continuous fiber reinforced ceramic matrix composites

Available in PDF, EPUB and Kindle. Book excerpt: The papers contained herein were presented at Euromech 204 'Structure and Crack Propagation in Brittle Matrix Composite Materials' held at Jablonna, Poland, from 12 to 15 November 1985. The Colloquium was organised and sponsored by The Institute of Fundamental Technological Research, Polish Academy of Sciences, under the auspices of the European Mechanics Committee (Euromech). The Euromech Committee is affiliated to the International Union of Theoretical and Applied Mechanics (IUT AM). IUT AM was organised early in the 1920s with the First Congress being held in Delft in 1924. The Euromech Colloquia were initiated some 20 years later with the intention of promoting European co-operation in the Mechanical Engineering Sciences. As the title implies, the Colloquium addressed a variety of problems associated with three main groups of materials, namely: high-strength composites, ceramics and cement-based materials, the common theme in each case being the relative brittleness of the matrix material. The problems considered ranged from fracture processes peculiar to such materials to projected design guidelines which will ensure their safe operation under a variety of conditions. Participants from thirteen countries (Czechoslovakia, France, FRG, GDR, Hungary, Italy, The Netherlands, Norway, Poland, Portugal, Sweden, UK, and USSR) contributed to the success of this event. For ease of reference, the 38 papers presented at the Colloquium have been subdivided into six distinct sections, viz. General Problems and Methods, Cracking in Ceramics, Fracture of Polymer Composites, Crack ing in Cement Based Composites, Fracture of Fibre Reinforced Cements and Fracture Mechanics of Concretes.

Download or read book Brittle Matrix Composites written by Francisco Montero and published by Elsevier Inc. Chapters. This book was released on 2012-11-12 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper a model is presented to simulate fracture of fibre reinforced cement based materials. The model is based on a lattice-type fracture model. Fibres are explicitly implemented as separate elements connected to the cement matrix via special interface elements. With the model multiple cracking and ductile global behaviour are simulated of the composite material. Variables in the model are the fibre dimensions and properties, the fibre volume in the composite, the bond behaviour of fibres and matrix and the cement matrix properties. These properties are obtained by testing, which will be described in the paper. The model is used as a design tool for creating fibre cement based composites with any desired mechanical behaviour.

Book Synopsis Brittle Matrix Composites by : Dominik Logoń
Download or read book Brittle Matrix Composites written by Dominik Logoń and published by Elsevier Inc. Chapters. This book was released on 2012-11-12 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main motivation for this work was the attempt to limit the rapid destruction of brittle high performance concrete UPC and, in consequence, to obtain SRCC (safe rope effect cement composite). In the high performance fiber reinforced cement composites HPFRC deflection and flexural strength are increased. The rope effect in HPFRC results in a highly deflected damaged specimen with multicracking effect and with post-peak load at bending exceeding that corresponding to the first crack, which enables to obtain cement composite with the ability to absorb additional energy after the appearance of the macrocrack. The SRCC paste and mortar were presented in the previous paper. This paper shows different effects of the strengthening of cement concrete with dispersed synthetic structural polypropylene fibers 19 and 54mm long. The possibility to control multicracking and the crack propagation process using the rope effect for SRCC composites, which eliminates the catastrophic process of the destruction of composite, was presented and a new possibility of the strengthening effects assessment was suggested.

Download or read book Cracks in composite materials written by George C. Sih and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composites offer great promise as light weight and strong materials for high performance structures. One of the major advantages of these materials as compared with metals is the basic way in which heterogeneity resist crack extension. In a fiber/matrix composite system, the fibers tend to cause cracks to form at closer spacing and delay the formation of a large crack. The enhancement of local failure such as fiber breaking, matrix cracking and interface debonding further reduces the energy level which might have otherwise reached the point of catastrophic failure. Even though substantial tests have been made on composite materials, little has been gained in the understanding and development of a predic tive procedure for composite failure. There are fundamental difficulties associated with incorporating the nonhomogeneous and anisotropic prop erties of the composite into the continuum mechanics analysis. Additional uncertainties arise from voids and defects that are introduced in the composite during manufacturing. Even a small quantity of mechanical imperfections can cause a marked influence on the composite strength. Moreover, the interface properties between the fibers and matrix or bonded laminae can also affect the load transmission characteristics significantly. It would be impossible to establish predictive procedures for composite failure unless realistic guidelines could be developed to control the manufacturing quality of composite systems.

Available in PDF, EPUB and Kindle. Book excerpt: This paper aims to get insight into the physical significance of the results obtained from curve fitting of a stochastic cracking model on experimental tensile stress-strain data of cementitious composites which are uniaxially reinforced with continuous fibre bundles of different kinds, such as glass, basalt, carbon, polyethylene and polyvinyl alcohol fibres. An experimental test program is performed on the different composites containing typically 20% in volume of fibres, as well on the fibre bundles themselves. A short introduction is given to the theory behind the stochastic cracking model, based on a Weibull distribution of the matrix cracking stress, which is used for modelling the experimental results. The obtained tensile stress–strain curves are analysed by means of curve fitting and an attempt is made to draw conclusions on the physical meaning of these results. The experimental results of tensile tests on specimens with an inorganic phosphate cement matrix containing the different fibre types, revealed a wide range of mechanical behaviour: carbon fibres result in a very stiff material, PE fibres in a very strong material, while the use of PVA fibres results in a very flexible and ductile composite. Curve fitting of the stochastic cracking model on the experimental data was successfully performed, leading to the identification of the Weibull model parameters. The reference cracking strength was found to be much higher than the mean matrix cracking strength. An interpretation, based on the phenomenon of crack suppression, is given for these high values compared to those found in literature for cement composites.
