This book presents the foundation and validation of the Cosserat Plate Theory, numerical experiments of deformation and vibration, and the unique properties of the Cosserat plates. Our approach incorporates the high accuracy assumptions of the Cosserat plate deformation consistent with the Cosserat Elasticity equilibrium equations, constitutive formulas, strain-displacement and torsion-microrotation relations. The Cosserat Plate Theory is parametric, where the "splitting parameter" minimizes the Cosserat plate energy. The validation of the theory is based on the comparison with the three-dimensional Cosserat Elastostatics and Elastodynamics. The numerical results are obtained using the Finite Element Method (FEM) specifically developed to solve the parametric system of equations. The analysis of deformation of a variety of Cosserat plates shows the stress concentration reduction, higher stiffness of Cosserat plates, and the size-effect related to the microstructure. The analysis of vibration of Cosserat plates predicts size-related properties of the plate vibration, the existence of the additional so-called Cosserat plate resonances, and the dynamic anisotropy, related to the dependency of the resonances on the microelement's shapes and orientations.

A state-of-the-art report prepared by RILEM Technical Committee 116-PCD. At present, durability of concrete is controlled by specifying the materials to be used, the methods of mixing, placing, curing and so on. This approach is often unsatisfactory and it is a common objective of concrete researchers and engineers to develop performance criteria which allow the potential durability of a particular concrete mix or structure to be estimated. However, the complexity of concrete as a material and the difficulty of developing consistent and reliable test methods has meant that progress has been slow. International interest in the subject is growing strongly with the development of international standards and so this book is very timely in giving an authoritative, international review of the subject. It will set the scene for the next few years as a key source of information and advice.

This book provides a comprehensive and authoritative review of durability of the frost resistance of concrete. It will enable both concrete materials specialists and practising engineers to better understand the deterioration processes which take place during freezing and thawing, and the effects of de-icing salts on concrete. It shows how test procedures can be used to provide worthwhile information and explains the many problems associated with their use. Durability of Concrete in Cold Climates explains how concrete can be designed and produced to be durable in cold environments, through careful selection of materials, mixture composition and proper use of air entrainment. It is fully illustrated with photographs and diagrams and contains over 250 references to sources and other publications. The main topics covered are: theories of frost ction and de-icer salt scaling mechanisms; laboratory tests; influence of materials and mix characteristics; air entrainment; field performance; and frost durability of dry concretes.

This text provides a review of the properties and use of the principal chemical admixtures for concrete, including over 250 references to key literature sources. Coverage of each admixture follows a standard format, so the reader is able to find relevant information on each type easily. The introductory chapter explains the interaction of admixtures in the cement-water system. The following four chapters deal with admixtures in common use: air extraining admixtures; hardening accelerators; high-range water reducers (superplasticizers); water reducing/retarding admixtures. Less commonly used admixtures are also discussed, including topics for special applications: anti-washout admixtures for underwater concrete; corrosion inhibitors; gas forming admixtures; pumping aids; shotcrete admixtures. This book should be of interest to concrete technologists worldwide in cement companies, ready mixed and precast concrete suppliers; admixture manufacturers (CAA members in UK); civil engineers; researchers and academics in civil engineering departments.

Guidance is provided on how to build DES models using the Arena, Simio and Simul8 simulation software, and tutorials for using the software are incorporated throughout. Simulation Modelling offers a uniquely practical and end-to-end overview of the subject, which makes it perfect required or recommended reading for advanced undergraduate and postgraduate students studying business simulation and simulation modelling as part of operations research, business analytics, supply chain management and computer science courses.

This is the first book devoted to a systematic description of the linear theory of piezoelectric shells and plates theory. The book contains two parts. In the first part, the theories for electroelastic thin-walled elements of arbitrary form with different directions of preliminary polarization are presented in an easy form for practical use. The approximate methods for integrating the equations of piezoelectric shells and plates are developed and applied for solving some engineering problems. In the second part, the theory of piezoelectric shells and plates is substantiated by the asymptotic method. The area of applicability for different kinds of electroelastic shell theories is studied. A new problem concerning the electroelastic phenomena at the edge of a thin-walled element is raised and solved.
The Theory of Piezoelectric Shells and Plates will be valuable to researchers working in the field of electroelasticity as well as to electrical and electronic engineers who use thin-walled piezoelements. It is also be helpful for students and post-graduates specializing in mechanics and for scientists concerning asymptotic methods.

Volume III extends this handbook series to cover new developments and topics in tribology that have occurred during the past decade. It includes in-depth discussions on revolutionary magnetic bearings used in demanding applications in compressors, high-speed spindles, and aerospace equipment. Extensive coverage is given to tribology developments in office machines and in magnetic storage systems for computers. Monitoring sensors are addressed in the first chapter, followed by chapters on specific monitoring techniques for automobiles, diesels, and rotating machines. One chapter is devoted to procedures used for tracking the remaining life of lubricants. Synthetic lubricants are discussed by outstanding specialists in this rapidly developing field. Synthetics are increasingly important in widely diverse areas, including compressors using the new ozone-layer-friendly refrigerants and a variety of extreme-temperature and environmentally-sensitive applications. Water- and gas-lubricated bearings are given similar attention. The contributors also develop a new, unified coverage for fatigue life of ball and roller bearings; for design and application of porous metal bearings; for self-contained lubrication, involving oil rings, disks, and wicks; and for plastic bearings. Each of these classes of bearings are used by the millions daily throughout industry.
The three-volume handbook is an essential reference to tribologists and lubrication, mechanical, and automotive engineers. It is invaluable to lubricant suppliers; bearing companies; those working in the aerospace industry; and anyone concerned with machine design, machinery wear, and maintenance.
