The Second International Symposium of Fatigue of Materials:Advances and Emergences in Understanding is a five-sessionsymposium held in conjunction with the Materials Science and Technology Conference 2012 (MS&T 2012) at Pittsburgh, Pennsylvania, during October 7-11, 2012. The abstracts that weresubmitted for presentation at this symposium cover a diverse rangeof topics. We have made an attempt to group these papers intosessions that focus on closely-related topics. However, as can beexpected, many of the papers could fit into more than one session.In the ensuing discussion, we provide a cohesive, complete andcompelling overview of the symposium as well as a summary of theabstracts that were submitted.
Session 1(Overview 1) and Session 2(Overview II) contain papers that
(i) Review the current state of knowledge both related andrelevant to the subject of fatigue behavior of materials, and
(ii) New, innovative, and emerging techniques for experimentalevaluation of the fatigue behavior.
In concurrence the papers attempt to analyze the data foraspects relevant to design and simultaneously predicting the usefullife of components and structures. Session 3 (Aerospace Materials I) and Session 4 (Aerospace Materials II) focus on advanced materials that are used inperformance-critical applications in the aerospace and automotiveindustries, such as the alloys of titanium, nickel, aluminum, andmagnesium. Session 5 is a collection of papers relating toother materials of engineering interest, such as iron andsteel, polymer, rubber, and even composites. In the summarypresented below, the session number and paper number are identifiedby S and P.
Topics related to the influence of both processing and theenvironment are covered in papers presented in all the sessions ofthis symposium, and are briefly summarized here as a group withadditional discussion included in the individual sessions.
