This book provides a comprehensive guidance for the use of sound statistical methods and for the evaluation of fatigue data of welded components and structures obtained under constant amplitude loading and used to produce S-N curves. Recommendations for analyzing fatigue data are available, although they do not deal with all the statistical treatments that may be required to utilize fatigue test results, and none of them offers specific guidelines for analyzing fatigue data obtained from tests on welded specimens. For an easy use, working sheets are provided to assist in the proper statistical assessment of experimental fatigue data concerning practical problems giving the procedure and a numerical application as illustration.

If you want to understand the long path to the climate crisis, read this book." –Deborah Coen, Professor of History and the History of Science and Medicine, Yale University Politicians and scientists have debated climate change for centuries in times of rapid change Nothing could seem more contemporary than climate change. Yet, in Chaos in the Heavens, Jean-Baptiste Fressoz and Fabien Locher show that we have been thinking about and debating the consequences of our actions upon the environment for centuries. The subject was raised wherever history accelerated: by the Conquistadors in the New World, by the French revolutionaries of 1789, by the scientists and politicians of the nineteenth century, by the European imperialists in Asia and Africa until the Second World War. Climate change was at the heart of fundamental debates about colonisation, God, the state, nature, and capitalism. From these intellectual and political battles emerged key concepts of contemporary environmental science and policy. For a brief interlude, science and industry instilled in us the reassuring illusion of an impassive climate. But, in the age of global warming, we must, once again, confront the chaos in the heavens.
This thesis presents several important aspects of the plasma dynamics in extremely high intensity electromagnetic fields when quantum electrodynamics effects have to be taken into account. This work is of utmost importance for the forthcoming generation of multipetawatt laser facilities where this physics will be tested. The first part consists of an introduction that extends from classical and quantum electrodynamics in strong fields to the kinetic description of plasmas in the interaction with such fields. This can be considered as an advanced tutorial which would be extremely useful to researchers and students new to the field. The second part describes original contributions on the analysis of the signatures of classical and quantum radiation reaction on the distribution function of the charged particles and of the photon spectrum, and leads to significant advances on this topic. These results are then extended to the analysis of the so-called QED cascades which are of central importance for a better understanding of some astrophysical phenomena and basic physics problems. Finally, the book discusses future directions for the high intensity laser–plasma interaction community. The results presented in this thesis are expected to become more and more relevant as the new multipetawatt facilities become operative.
