This book focuses on the vibration behavior of ceramic-matrix composites (CMCs), including (1) vibration natural frequency of intact and damaged CMCs; (2) vibration damping of CMCs considering fibers debonding and fracture; (3) temperature-dependent vibration damping of CMCs; (4) time-dependent vibration damping of CMCs; and (5) cyclic-dependent vibration damping of CMCs. Ceramic-matrix composites (CMCs) possess low material density (i.e., only 1/4 or 1/3 of high-temperature alloy) and high-temperature resistance, which can reduce cooling air and improve structure efficiency. Understanding the failure mechanisms and internal damage evolution represents an important step to ensure reliability and safety of CMCs. Relationships between microstructure, damage mechanisms, vibration natural frequency, and vibration damping of CMCs are established. This book helps the material scientists and engineering designers to understand and master the vibration behavior of CMCs at room and elevated temperatures.

Armorial porcelains comprised the output of most European ceramics factories in the 18th and 19th Centuries in response to the large quantity of armorial porcelain services that were being imported from China bearing the coats of arms and crests of aristocratic families. Whereas these armorial services have been identified and covered for most porcelain manufactories the information relevant to their production by the two relatively short-lived Nantgarw and Swansea China Works has not been addressed as a theme until now. As an integral  component  of  the holistic forensic appraisal of porcelain, a functional and decorative artwork manifestly part of our cultural heritage and its ongoing preservation ,  the recording and identification of such artefacts is material for the future establishment of a database of factory production . The Nantgarw and Swansea factories only operated for a limited period in the second decade of the 19th Century and their porcelains were much appreciated  for their high quality and desirability by Georgian households. Today, examples are to be found in many museums and  ceramics collections and continue to excite the interest of specialists and the general public . This text provides the first comprehensive assessment of armorial porcelains from these two factories and the methodology and procedure for the identification of unknown armorial bearings and crests is illustrated; individual bearings are discussed  in detail and existing incorrect assignments in the literature are re-appraised. The difficulties in attribution of armorial heraldic achievements that are only minimally depicted are considered and directions for further studies using historical documentation are invoked. This book therefore fills a currently existing gap in the ceramics literature of the 19th Century.

Heraldic devices first appeared on ceramics in Western Europe from the sixteenth century onwards; however, it was not until the 1760s that British ceramic manufactories began executing commissions for services displaying heraldic devices for the gentry. This book explores the rise of the new gentry class and the market for armorial services through the case study of the Pendock Barry service. The case study is presented from three angles. It looks at Pendock Neale Barry (1757¿1833) who commissioned the service, then considers the evidence for attributing the service to the Derby factory during the period 1805¿1810, and finally looks at the evidence supporting an attribution of the decoration to Billingsley. The case study sets out a novel approach to understanding heraldic devices on ceramics by bringing together the disciplines of detailed genealogical research, cultural knowledge, and chemical analytical compositional data. This multidisciplinary approach enables the armorial services to be considered and understood through the lens of heritage, culture, and science.

This book focuses on the matrix cracking behavior in ceramic-matrix composites (CMCs), including first matrix cracking behavior, matrix cracking evolution behavior, matrix crack opening and closure behavior considering temperature and oxidation. The micro-damage mechanisms are analyzed, and the micromechanical damage models are developed to characterize the cracking behavior. Experimental matrix cracking behavior of different CMCs at room and elevated temperatures is predicted. The book can help the material scientists and engineering designers to better understand the cracking behavior in CMCs.

This book covers the discovery and the results of the analytical study of the composition of the Farnley Hall service, involving both the embossed moulding and the decorative compositions. The discovery of this missing porcelain service, which was manufactured 200 years ago, is a modern detective story in the preservation of cultural heritage, whilst its physical analysis has identified some new data that need to be incorporated into correcting and expanding the literature that is used for the differentiation of porcelains by ceramic historians and museum conservators. The importance of the Farnley Hall service discovery is that it provides the only example of such a Nantgarw Porcelain service that still resides in its original place of usage from 200 years ago: it is therefore a unique example and is a very important part of our national cultural heritage. It provides an illustration of the data that can be accessed from the application of inductive reasoning to elicit novel information about a manufactory whose work books no longer exist and its comparison with contemporary manufactories in the late eighteenth and early nineteenth centuries. The concepts can be appreciated by experts and also by non-technical readers. This is the first time that such a detailed research approach has been adopted for any comparative ceramic project. The book is therefore relevant for a specialist and non-specialist readership, including museum ceramics curators and collectors of the genre.

The design of treatments for the conservation of stone in historical buildings and works of art is a challenging task, as a deep understanding of the working properties and performance of the available products and methods is required to tackle complex decay patterns.The chapters in this book illustrate the state of the art on traditional and innovative materials and methods for stone conservation, examining current trends and future perspectives. Each of them is focused on describing the consequent phases that complement the spectrum of the conservation intervention: preliminary investigations, condition assessment, and mapping of the deterioration patterns; surface cleaning, with a specific focus on laser technology; consolidation; protection; repair mortars and grouts; and onsite assessment and monitoring of conservation treatments. The performance of the applied conservation interventions is criticized and discussed with an aim of providing the specialists with specific tools for stone conservation.   This book intends to bridge the gap between laboratory studies and conservation interventions, by linking together the diverse scientific areas involved in the preservation of stone heritage. Different case studies are included, highlighting specific conservation challenges and their solutions in order to understand and overcome them. The aim is to guide conservators, conservation scientists and heritage stakeholders in the selection of compatible and sustainable materials and techniques for Conserving Stone Heritage.
