Nonlocal Euler-Bernoulli Beam Theories: A Comparative Study by Jingkai Chen
English | EPUB | 2021 | 64 Pages | ISBN : 3030697878 | 11.7 MB
This book presents a comparative study on the static responses of the Euler-Bernoulli beam governed by nonlocal theories, including the Eringen's stress-gradient beam theory, the Mindlin's strain-gradient beam theory, the higher-order beam theory and the peridynamic beam theory. Benchmark examples are solved analytically and numerically using these nonlocal beam equations, including the simply-supported beam, the clamped-clamped beam and the cantilever beam. Results show that beam deformations governed by different nonlocal theories at different boundary conditions show complex behaviors. Specifically, the Eringen's stress-gradient beam equation and the peridynamic beam equation yield a much softer beam deformation for simply-supported beam and clamped-clamped beam, while the beam governed by the Mindlin's strain-gradient beam equation is much stiffer.

The latest generation of high-power pulsed lasers has renewed interest in the ultra-relativistic effects produced by the interaction between laser beams and electrons. Synthesising previous research, this book presents a unitary treatment of the main effects that occur in the ultra-relativistic interactions between laser beams and electrons. It uses exact solutions of relativistic and classical quantum equations, including a new solution of the Dirac equation, to fully describe the field and model the main ultra-relativistic effects created within it. Aimed at scientists, graduate students and professionals working in high-power laser facilities and labs, as well as those studying relativistic optics, the book presents a comprehensive survey of the field, intended to facilitate high-level engagement.

Fast Transverse Beam Instability Caused by Electron Cloud Trapped in Combined Function Magnets by Sergey A. Antipov
English | EPUB| 2018 | 95 Pages | ISBN : 3030024075 | 19.2 MB
This thesis presents profound insights into the origins and dynamics of beam instabilities using both experimental observations and numerical simulations. When the Recycler Ring, a high-intensity proton beam accelerator at Fermi National Accelerator Laboratory, was commissioned, it became evident that the Recycler beam experiences a very fast instability of unknown nature. This instability was so fast that the existing dampers were ineffective at suppressing it. The nature of this phenomenon, alongside several other poorly understood features of the beam, became one of the biggest puzzles in the accelerator community.

Saied Muhammed Hassan Darwish, Naveed Ahmed, Abdulrahman M. Al-Ahmari, "Laser Beam Micro-milling of Micro-channels in Aerospace Alloys"
English | 2017 | pages: 368 | ISBN: 9811036012 | PDF | 15,1 mb
This volume is greatly helpful to micro-machining and laser engineers as it offers obliging guidelines about the micro-channel fabrications through Nd:YAG laser beam micro-milling. The book also demonstrates how the laser beam micro-milling behaves when operating under wet conditions (under water), and explores what are the pros and cons of this hybrid technique. From the predictive mathematical models, the readers can easily estimate the resulting micro-channel size against the desired laser parametric combinations. The book considers micro-channels in three highly important research materials commonly used in aerospace industry: titanium alloy Ti-6Al-4V, nickel alloy Inconel 718 and aluminum alloy AA 2024. Therefore, the book is highly practicable in the fields of micro-channel heat exchangers, micro-channel aerospace turbine blades, micro-channel heat pipes, micro-coolers and micro-channel pulsating heat plates. These are frequently used in various industries such as aerospace, automotive, biomedical and micro-electronics.
