The formalism processing of unbuckled solids mechanics involves several mathematical tools which are to be mastered at the same time. This volume collects the main points which take place in the course of the formalism, so that the user immediately finds what he needs without looking for it.

In this book, the authors present in detail several recent methodologies and algorithms that they developed during the last fifteen years. The deterministic methods account for uncertainties through empirical safety factors, which implies that the actual uncertainties in materials, geometry and loading are not truly considered.

Polymer composites are often submitted to severe humid environmental conditions during their service life. Moisture absorption by the polymer matrix induces various multiphysics effects that can significantly impair the functions and durability of the mechanical parts: weight gain, plasticization (reversible loss of mechanical properties, i.e. stiffness and ultimate strength), hygroscopic strains (volume change) and, eventually, damage. Most of these phenomena induced by the internal distribution of water also affect the moisture absorption process. This book is focused on the multi-scale coupled effects occurring during moisture absorption by polymer composites.

The main objective of this book is to provide to mechanical scientists and engineers the kinetic modeling tools necessary for predicting the damage state of organic composite matrices submitted to hydrolytic and oxidative ageing. These tools are derived from the degradation mechanisms and their validity is successfully checked from many experimental data. They can be interfaced with existing or under development computer codes for predicting the lifetime of composite structures. Particular attention is paid to the relationships between damage state and use properties in view of defining structural end-of-life criteria. For this purpose the book is divided into three main parts. The first one is devoted to the presentation of the common aspects to all types of chemical degradation processes. Emphasis is put on specific aspects of composite structures, such as the role of interphase/interface or the anisotropy of reagent diffusion, but also on current issues in the field of material ageing such as the study of multiphysics couplings. The second part is focused on humid ageing. Physical processes linked to plasticization and swelling, are distinguished from chemical processes in particular from the matrix hydrolysis and its resulting damages at the microstructural scale (osmotic cracking, blistering, etc.). The third part concerns thermal ageing. The ultimate objective is to predict the consequences of thermal oxidation on thermomechanical properties of organic composite matrices, in particular on their glass transition temperature and elastic and fracture properties. In each part, the kinetic approach is illustrated by several practical examples.

This book covers several aspects of the fatigue behavior of textile and short fiber reinforced composites. The first part is dedicated to 2D and 3D reinforced textile composites and includes a systematic description of the damage evolution for quasi-static and tensile-tensile fatigue loadings.

In this book, two kinds of analysis based on acoustic emission recorded during mechanical tests are investigated. In the first, individual, analysis, acoustic signature of each damage mechanism is characterized. So with a clustering method, AE signals that have similar shapes or similar features can be group together into a cluster. Afterwards, each cluster can be linked with a main damage. The second analysis is based on a global AE analysis, on the investigation of liberated energy, with a view to identify a critical point. So beyond this characteristic point, the criticality can be modeled with a power-law in order to evaluate time to failure.

The book focuses on the effect of ageing (thermo-oxidation, humid ageing) on the mechanical properties of organic matrix composite materials, covering: Bibliographic issues and a detailed state-of-the-art; phenomenological and experimental issues; modelling issues and models parameter identification; illustration and interpretation of experimental tests and proposal for novel test design in the light of the model predictions.

Where do the digital humanities really come from? Are they really news? What are the theoretical and technical influences that participate in this scientific field that arouses interest and questions? This book tries to show and explain the main theories and methods that have allowed their current constitution. The aim of the book is to propose a new way to understand the history of digital humanities in a broader perspective than the classic history with the project of Robert Busa. The short digital humanities perspective neglects lots of actors and disciplines. The book tries to show the importance of other fields than humanities computing like scientometry, infometry, econometry, mathematical linguistics, geography and documentation.

In an uncertain economy where business risk is significant, the company tends to rely more on its environment than to invest, for example, in all steps of technological creation; This can be explained by the fact that investments in the acquisition (ownership) of production resources are less expensive than those implied in the formation of these resources; which also explains the attractiveness (in an open economy) of regions with abundant scientific and technical resources. To understand and analyze the innovation process in order to better design and launch new goods, services and technologies, one has to consider the creative dimension of the individual, the business and the organization in general. In new approaches to innovation, the entrepreneur and the company are analyzed through their skills, and their function of resource generation; Innovation thus becomes endogenous, gradual or radical, integrated in a complex process with many feedbacks and interactions. The innovative organization (small or large) is presented in this book as a dynamic system composed of specific and diverse skills (including those of the contractor, engineers or managers). By acquiring, combining and mobilizing these skills, the innovative agent (entrepreneur or company) can create technological resources and develop relations with its environment. Hence the importance of management in design, implementation, protection of intellectual property as well as of the development of new goods, services and technology, commercial and organizational models.

"Creative competitive intelligence" is an information-seeking and monitoring activity of an information environment for the purpose of creativity and innovation. It involves the process leading up to the development of an informational supply adapted to the inspiration of creative or innovative personnel.

As a theory, sociobiology is opposed to socio-ecology, a discipline hampered since its birth. The indictment of the ideological intentions of the first has obscured the notion that the growing domination of the image of the selfish gene has obstructed the necessary rise of the second.

Earthquake Occurrence provides the reader with a review of algorithms applicable for modeling seismicity, such as short-term earthquake clustering and pseudo-periodic long-term behavior of major earthquakes.

Manufacturing industries strive to improve the quality and reliability of their products, while simultaneously reducing production costs.

This book presents the economic theories with regards to the entrepreneur of yesterday and those of more recent years, on which issue research has been developing exponentially since the last third of the 20th Century. Much of this book will be devoted to contemporary theories.

This book founds its main argument on the fact that the Industrial Revolution socio-economic models are now irrevocably shifting towards a new order (whatever the naming for it). Old notions with Growth as a chief example have by now become corroded , i.e. altered by a changing global environment.

Practices associated with the culture of scholarly reading have been developed over many centuries and annotations themselves have become the subject of study, either as additional elements in connection with the original texts or as documents in their own right.

Everyone, whether they like it or not, is exposed to electromagnetic fields, most of the time, at very low levels. In this case, they are inconsequential, but they can cause adverse health effects when they become intense enough. This topic is complex and sensitive.

Innovation mobilizes complex process in which the imaginary intervenes at various levels. If it is difficult for some players to assert who, science or science fiction is the source of innovations, new technology or new product is part of a fantasy that accompanies its invention, its design and diffusion.

SEO practices for Baidu and other Chinese search engines are little known in the Western world. However, in order for a company to promote itself successfully in the Middle Kingdom, it is absolutely necessary to go online in China.
