Continuum and Computational Mechanics for Geomechanical Engineers (ISRM Book Series #1)
by Ömer AydanThe field of rock mechanics and rock engineering utilizes the basic laws of continuum mechanics and the techniques developed in computational mechanics. This book describes the basic concepts behind these fundamental laws and their utilization in practice irrespective of whether rock/rock mass contains discontinuities. This book consists of nine chapters and six appendices. The first four chapters are concerned with continuum mechanics aspects, which include the basic operations, definition of stress and strain tensors, and derivation of four fundamental conservation laws in the simplest yet precise manner. The next two chapters are the preparation for computational mechanics, which require constitutive laws of geomaterials relevant to each conservation law and the procedures for how to determine required parameters of the constitutive laws. Computational mechanics solves the resulting ordinary and partial differential equations. In Chapter 7, the methods of exact (closed-form) solutions are explained and they are applied to ordinary/partial differential equations with solvable boundary and initial conditions. In Chapter 8, the fundamentals of approximate solution methods are explained for one dimension first and then how to extend them to multi-dimensional problems. The readers are expected to learn and clearly understand how they are derived and applied to various problems in geomechanics. The final chapter involves the applications of the approximate methods to the actual problems in practice for geomechanical engineers, which cover the continuum to discontinuum, including the stress state of the earth as well as the ground motions induced by earthquakes. Six appendices are provided to have a clear understanding of continuum mechanics operations and procedures for how to deal with discontinuities/interfaces often encountered in rock mechanics and rock engineering.
Continuum Damage Mechanics: A Continuum Mechanics Approach to the Analysis of Damage and Fracture (Solid Mechanics and Its Applications #185)
by Sumio MurakamiRecent developments in engineering and technology have brought about serious and enlarged demands for reliability, safety and economy in wide range of fields such as aeronautics, nuclear engineering, civil and structural engineering, automotive and production industry. This, in turn, has caused more interest in continuum damage mechanics and its engineering applications. This book aims to give a concise overview of the current state of damage mechanics, and then to show the fascinating possibility of this promising branch of mechanics, and to provide researchers, engineers and graduate students with an intelligible and self-contained textbook. The book consists of two parts and an appendix. Part I is concerned with the foundation of continuum damage mechanics. Basic concepts of material damage and the mechanical representation of damage state of various kinds are described in Chapters 1 and 2. In Chapters 3-5, irreversible thermodynamics, thermodynamic constitutive theory and its application to the modeling of the constitutive and the evolution equations of damaged materials are descried as a systematic basis for the subsequent development throughout the book. Part II describes the application of the fundamental theories developed in Part I to typical damage and fracture problems encountered in various fields of the current engineering. Important engineering aspects of elastic-plastic or ductile damage, their damage mechanics modeling and their further refinement are first discussed in Chapter 6. Chapters 7 and 8 are concerned with the modeling of fatigue, creep, creep-fatigue and their engineering application. Damage mechanics modeling of complicated crack closure behavior in elastic-brittle and composite materials are discussed in Chapters 9 and 10. In Chapter 11, applicability of the local approach to fracture by means of damage mechanics and finite element method, and the ensuing mathematical and numerical problems are briefly discussed. A proper understanding of the subject matter requires knowledge of tensor algebra and tensor calculus. At the end of this book, therefore, the foundations of tensor analysis are presented in the Appendix, especially for readers with insufficient mathematical background, but with keen interest in this exciting field of mechanics.

Continuum Mechanics and Linear Elasticity: An Applied Mathematics Introduction (Solid Mechanics and Its Applications #238)
by Ciprian D. ComanThis is an intermediate book for beginning postgraduate students and junior researchers, and offers up-to-date content on both continuum mechanics and elasticity. The material is self-contained and should provide readers sufficient working knowledge in both areas. Though the focus is primarily on vector and tensor calculus (the so-called coordinate-free approach), the more traditional index notation is used whenever it is deemed more sensible.With the increasing demand for continuum modeling in such diverse areas as mathematical biology and geology, it is imperative to have various approaches to continuum mechanics and elasticity. This book presents these subjects from an applied mathematics perspective. In particular, it extensively uses linear algebra and vector calculus to develop the fundamentals of both subjects in a way that requires minimal use of coordinates (so that beginning graduate students and junior researchers come to appreciate the power of the tensor notation).

Contracting and Safety: Exploring Outsourcing Practices in High-Hazard Industries (SpringerBriefs in Applied Sciences and Technology)
by Jan Hayes Stéphanie TillementThis open access book examines the increase in outsourcing, contracting and subcontracting as ways of organising work. It explores the impact of these employment arrangements on public safety, particularly when they are linked to complex supply networks in a range of engineering industries including oil and gas, nuclear power and aviation. The brief provides practical recommendations on how best to manage arrangements that target short-term profitability and also maintain excellence in long-term safety outcomes. The brief is a source of advice for organisations on how to maximise the benefits and minimise long-term system reliability issues that can be introduced by contracting and outsourcing, rather than assuming it to be a wholly negative or positive practice. Contracting and Safety comprises qualitative, empirical studies focusing on high-reliability organisation. As such, this brief provides a rich picture of the experience of working in complex supply chains. It will be of interest to researchers in industrial safety, as well as safety professionals and project managers within engineering industries.
Contractor Health and Safety Compliance for Small to Medium-Sized Construction Companies
by Zakari Mustapha Clinton Aigbavboa Wellington ThwalaThis book explores the formation of small and medium-sized construction company's (SME) compliance with health and safety issues in developing countries. Little has been written about the formation of SME contractors' health and safety compliance for developing countries, especially, in the sub-sahara regions where construction and infrastructure development activities have significantly increased in order to serve the development mandate of those countries. Thus, this book will provides insight into construction safety for SMEs, as well as health and safety compliance, and its policy implementation trends and development.
Contractor Safety Management

Contractors and War: The Transformation of US Expeditionary Operations
by Christopher Kinsey Malcolm Hugh PattersonThe U. S. military is no longer based on a Cold War self-sufficient model. Today's armed forces are a third smaller than they were during the Cold War, and yet are expected to do as much if not more than they did during those years. As a result, a transformation is occurring in the way the U. S. government expects the military to conduct operations-with much of that transformation contingent on the use of contractors to deliver support to the armed forces during military campaigns and afterwards. Contractors and Warexplains the reasons behind this transformation and evaluates how the private sector will shape and be shaped by future operations. The authors are drawn from a range of policy, legislative, military, legal, and academic backgrounds. They lay out the philosophical arguments supporting the use of contractors in combat and stabilization operations and present a spectrum of arguments that support and criticize emergent private sector roles. The book provides fresh policy guidance to those who will research, direct, and carry out future deployments.

Contracts for Engineers: Intellectual Property, Standards, and Ethics
by Robert D. HunterEngineers encounter different types of contracts at nearly every turn in their careers. Contracts for Engineers: Intellectual Property, Standards, and Ethics is a tool to enhance their ability to communicate contractual issues to lawyers—and then better understand the legal advice they receive. Building on its exploration of contracts, this book expands discussion to: Patents, copyrights, trademarks, trade secrets, and other intellectual property issues Development of standards and the bodies that govern them, as well as conformity assessment and accreditation Ethics at both the micro and macro levels—a concept under major scrutiny after several major disasters, including the Gulf of Mexico oil spill, the collapse of Boston’s Big Dig, and a coal-mining accident that resulted in many deaths With a brief introduction to common law contracts and their underlying principles, including basic examples, the book presents a sample of the Uniform Commercial Code (UCC) regarding the sale of goods. It evaluates elements of the different contracts that engineers commonly encounter, such as employee and associated consulting agreements and contracts involved in construction and government. Approaching intellectual property from a contract perspective, this reference focuses on the many different types of patents and their role in commerce. It touches on the application of trademarks and recent developments in the use of copyright as a form of contract and explains the process of obtaining patents, including the rationale for investing in them. Ethical standards receive special attention, which includes a review of several prominent professional codes of ethics and conduct for both organizations and individual engineers, particularly officers and higher-level managers.
Contractual Management: Managing Through Contracts
by Ralph Schuhmann Bert EichhornThe Concept Contractual Management offers a holistic approach to managerial decision-making based on contracts or business processes that are related to contracts.
