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 International Symposium in Brittle Matrix Composites October 13-15, 2003 covers a wide spectrum of topics including cement based composites, ceramic composites and brittle polymer matrix composites. In the papers various topics and issues are considered such as: analytical and numerical studies related to the design of composites, prediction of behaviour and verification of strength and stability, testing methods, manufacturing processes and repair, environmental effects and durability assessment. The present volume of 55 papers proves that there are still many problems in the field of brittle matrix composites deserving theoretical and experimental investigations and that new solutions to these problems are needed for practical application in civil engineering, industrial structures, machinery and other domains.

Available in PDF, EPUB and Kindle. Book excerpt: Particle packing has been recognized to influence mechanical and durability properties of cementitious materials, which are generally favored by optimum packing density. Particle size is a common denominator in such studies. Unfortunately, so far, particle shape has not been extensively and unambiguously evaluated in these approaches. Part of it is definitely due to the interconnected nature of size and shape as well as the missing of a clear methodological framework. Nevertheless, various strategies for assessment of shape are available. Capabilities of available advanced computer-simulation systems render possible considering differently-shaped particles. This will make it possible studying in an economic way the effect of shape on properties of densely packed aggregate or binder particles at low w/c ratios. So, shape assessment is becoming an even more relevant issue in structural studies of concrete. This paper presents a somewhat underrated approach to the assessment of shape of (aggregate) particles, i.e. Fourier analysis. A new shape index is proposed.

Available in PDF, EPUB and Kindle. Book excerpt: In understanding the complexity of the fracture mechanics of brittle matrix composites, knowing reliable values of the mechanical properties of the fiber-matrix interface are important. Since all experiments designed to evaluate the mechanical properties of the fiber-matrix interface rely on curve fitting experimental measurements to analytical results, accurate physical modeling of these tests is imperative. In this final report, two common tests, namely the push-in test and the slice compression test, were analytically simulated. In the push-in test, the effect of extrinsic factors such as indentor shape and size, and push-through radius hole, and intrinsic factors such as transverse isotropy of fibers on load-displacement curves was studied. All factors except the push through hole-radius were found to affect the load-displacement curves. In the slice compression test, comparison was made for the values of maximum protrusion, residual protrusion and debond lengths for a simple shear-lag analysis and a finite element analysis model. Large differences ranging from 15% to 70% were found by using the two different models. Hence, the importance of accurate modeling of the test cannot be ignored. The study also gives tools to an experimentalist for designing reliable experiments for evaluating reliable values of the mechanical properties of the fiber-matrix interface.

This book was released on 2021-04-19 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified approach to fracture behavior of natural and synthetic fiber-reinforced polymer composites on the basis of fiber orientation, the addition of fillers, characterization, properties and applications. In addition, the book contains an extensive survey of recent improvements in the research and development of fracture analysis of FRP composites that are used to make higher fracture toughness composites in various applications.The FRP composites are an emerging area in polymer science with many structural applications. The rise in materials failure by fracture has forced scientists and researchers to develop new higher strength materials for obtaining higher fracture toughness. Therefore, further knowledge and insight into the different modes of fracture behavior of FRP composites are critical to expanding the range of their application.

Available in PDF, EPUB and Kindle. Book excerpt: More recent investigations on cellulose-cement composites predominantly deal with durability aspects, whereby use is made of accelerated weathering cycles as the main approach to establishing the deterioration mechanisms and the efficiency of treatment methods. As moisture transport is the main mechanism that leads to the deterioration of those composites, accelerated ageing tests are commonly based on wet-drying cycles with a combination of temperature and relative humidity (R.H.) variations. Both variables result in dimensional changes of the samples, leading to interfacial abrasion and the progressive decrease in the composites’ toughness and strength. To investigate the effects of each of these variables, the weathering tests were performed in an environmental chamber considering each variable separately in two ageing cycles. In the first one the composites were submitted to saturation and drying at a constant 25°C, by means of a relative humidity change in the chamber. For the second ageing cycle a temperature variation between 20°C and 60°C at a constant R.H. of 50% was applied. The effects of each ageing cycle on the cellulose-cement composites were assessed on the basis of physical and mechanical parameters, determined after 0, 5, 20 and 50 cycles. Moreover, part of the samples was provided with electrical strain gauges, which rendered possible to determine the composites’ expansion-shrinkage behaviour during the temperature and R.H. variations. As the main treatment approach, the partial replacement of cement (OPC) by rice husk ash (RHA) was investigated. It was found that RHA improved the strength and durability performance of the composites, although the increased porosity resulted from the 30% replacement rate of OPC and carbonate filler by RHA.

Available in PDF, EPUB and Kindle. Book excerpt: This is the third volume published in the series of proceedings of international symposia called 'Brittle Matrix Composites' organised every three years in Poland. The first Symposium, denoted as BMC1, was organised in Jablonna near Warsaw in 1985 under the auspices of the European Mechanics Committee (EUROMECH 204). The second (BMC2) took place in Cedzyna near Kielce in 1988; the present (BMC3) is being held in Warsaw in September 1991. The BMC Symposia are intended to cover mechanical problems related to three main groups of composite materials: high-strength composites, ceramics and cement-based materials. The common feature which is a link between these materials is their brittle behaviour. Brittleness has no clear definition, but it is considered as an important potential disadvantage of every material. Brittle fracture creates various situations which may be very dangerous for the safety and serviceability of structures manufactured from composite materials. Also the brittleness of non-structural elements may give rise to disadvan tageous behaviour, e.g. during transportation and montage. There are many structural and technological ways of reducing material brittleness. Their development and further improvement are of primordial importance for most applications of these composite materials. The problems considered in the series of BMC Symposia cover all aspects of brittle matrix composites: • design studies, theoretical considerations, computational methods; • prediction of behaviour, fracture mechanics and other approaches; • testing methods, test results, all types of experimental studies; • manufacturing processes, applications, observations and durability assess ments, environmental effects, etc.
