Machining and Cold Work -- Chapter III. Materials and Structures, III.1. Fatigue and Fracture, III.2. Films, Coatings and Oxides, III.3. Composites and Nano/Micro Structures Keyword: residual stresses in engineering materials: measurement and modeling techniques, manufacturing processes, consequences on fatigue life or distortions, coupling with oxidation phenomena or occurrence at microscopic or submicroscopic scale In this collection of 157 peer-reviewed papers from a July 2014 conference held in France, international contributors in manufacturing technology and materials science report on the latest understanding of residual stresses that negatively impact the strength and safety of materials and structures at the macroscopic, phase, grain, and atomic scales. Section 1 on measurement contains sub-sections on local scale measurements, diffraction at grain scale and multistate diffraction, diffraction gradients and instrumental developments, mechanical relaxation methods, and acoustics and electromagnetics methods. Section 2 on manufacturing and materials processing contains subsections on welding, heat treatment and phase transformation, and machining and cold work. Section 3 deals with aspects of materials and structures, such as fatigue and fracture, films and coatings, oxides, composites, and nano- and microstructures. The book includes b&w photos and images. -- Architectural engineering-- Materials science-- Mechanical engineering.
