This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail porte sur l'étude expérimentale et numérique de la fissuration et du cloquage induits par l'hydrogène dans des polycristaux de fer déformés plastiquement. Des essais mécaniques de traction et de cisaillement jusqu'à de grandes déformations plastiques ont été effectués sur le fer Armco, suivis de chargement cathodique en hydrogène. Le cloquage et la fissuration induites ont été caractérisés à différentes échelles, à l'aide de la surfométrie et d'analyses MEB-EBSD. Les résultats montrent la réduction du cloquage avec la déformation plastique et l'influence du mode de chargement mécanique avant chargement en hydrogène sur les caractéristiques des cloques et de la fissuration. Les fissures induites par l'hydrogène sont majoritairement transgranulaires et correspondent statistiquement avec les traces de plans de glissement du fer.Des simulations éléments finis de diffusion-piégeage après différents chargements mécaniques on tété effectuées pour mettre en évidence l'effet de la prédéformation sur la distribution d'hydrogène dans le matériau. Une modélisation phénoménologique de la croissance de pores sous pression interne a été proposée pour mettre en évidence de l'effet du mode de sollicitation sur le cloquage, en corrélation avec les tendances expérimentales.

Book Synopsis Fracture Mechanics by : Ted L. Anderson
Download or read book Fracture Mechanics written by Ted L. Anderson and published by CRC Press. This book was released on 2005-06-24 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: With its combination of practicality, readability, and rigor that is characteristic of any truly authoritative reference and text, Fracture Mechanics: Fundamentals and Applications quickly established itself as the most comprehensive guide to fracture mechanics available. It has been adopted by more than 100 universities and embraced by thousands of professional engineers worldwide. Now in its third edition, the book continues to raise the bar in both scope and coverage. It encompasses theory and applications, linear and nonlinear fracture mechanics, solid mechanics, and materials science with a unified, balanced, and in-depth approach. Reflecting the many advances made in the decade since the previous edition came about, this indispensable Third Edition now includes: A new chapter on environmental cracking Expanded coverage of weight functions New material on toughness test methods New problems at the end of the book New material on the failure assessment diagram (FAD) method Expanded and updated coverage of crack closure and variable-amplitude fatigue Updated solutions manual In addition to these enhancements, Fracture Mechanics: Fundamentals and Applications, Third Edition also includes detailed mathematical derivations in appendices at the end of applicable chapters; recent developments in laboratory testing, application to structures, and computational methods; coverage of micromechanisms of fracture; and more than 400 illustrations. This reference continues to be a necessity on the desk of anyone involved with fracture mechanics.
Book Synopsis TRIBO-FATIGUE by : Leonid A. Sosnovskiy
Download or read book TRIBO-FATIGUE written by Leonid A. Sosnovskiy and published by Springer Science & Business Media. This book was released on 2010-06-14 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue and wear are the most damaging phenomena affecting machines since they result in some 90% of breakdowns. This tutorial book systematically develops a unified overview, named tribo-fatigue, which aims to address the complex wear-fatigue damages. Tribo-fatigue synthesizes aspects of three disciplines: mechanical fatigue, tribology, and reliability of mechanical systems. Tribo-fatigue opens new perspectives for increasing the durability of machines according to the most important criteria of their serviceability. Detailed damage measurement and wear-fatigue tests that enable engineers to design more durable and reliable systems are developed. The book is intended for advanced students, researchers and engineers.
