Sommario/riassunto |
|
Is there a fatigue limit in metals? This question is the main focus of this book.<br /> Written by a leading researcher in the field, Claude Bathias presents a thorough and authoritative examination of the coupling between plasticity, crack initiation and heat dissipation for lifetimes that exceed the billion cycle, leading us to question the concept of the fatigue limit, both theoretically and technologically.<br /> This is a follow-up to the Fatigue of Materials and Structures series of books previously published in 2011.<br /> Contents 1. Introduction on Very High Cycle Fatigue.<br /> 2. |
