Fundamentals Of Metal Fatigue Analysis

Applied loads are rarely static, but rather variable in nature. This causes fatigue damage. The problem is why, where and when fatigue loads reach such a level as to threaten and eventually compromise the strength of materials and structures. The knowledge of these fundamental questions, from the early microscopic signs to the final macroscopic appearance of irreversible damage, represents the necessary basis for any effective fatigue safe design and life extension of structures. Moreover, fatigue damage leaves permanent signs on the metal surface that, like fingerprints, reveal both the culprit and the reasons of the crime.

Description

This course examines the concepts of fatigue and damage in materials and structures subjected to cyclic loads, as well as provides practical tools for practicing engineers.


Who Should Attend

Engineers and other professionals interested in fatigue damage and cyclic failure.


Objectives

 At the end of this workshop the participants should be able to:

  • Demonstrate a comprehensive understanding of the fundamental concepts and theories of fatigue;
  • Adopt useful analytical methods to undertake fatigue calculations, prevent fatigue failures;
  • Recognize the causes of failures through post mortem analysis of failed structures.

Topics Covered

  • Introduction to fatigue mechanism
  • Cyclic softening or hardening of materials
  • Slip-based models of fatigue and damage nucleation
  • The fatigue limit concept
  • Effect of mean stress
  • Cyclic load spectra and cycle counting
  • Fatigue damage progression and accumulation
  • Notch effect and Neuber rule
  • Fatigue in welds and joints
  • Design procedures
  • Optical and SEM techniques to recognize fatigue features and causes.

Facilitator

Prof. Pietro Paolo Milella has been responsible for the licensing of nuclear power plants and of all Water Reactor Nuclear Safety Research and Development Programs in Italy in the mechanical field, from 1978 to 1994.  Presently, adjunct professor at the university of Cassino (Rome), he has been teaching Fracture Mechanics , Metallurgy and Machine Design.

Prof. Milella published two textbooks in Italian on Fracture Mechanics and Electric Arc Furnace Steel Production and a textbook in English on Fatigue and Corrosion in Metals. He is active in industrial consultancy and advanced fatigue, fracture and corrosion research for various industries. Prof. Milella has more than 100 scientific publications and has been ASME member, PVRC member, member of OECD-PWG 3 on structural integrity, member of the IAEA International Working Group on Reliability of Pressure Water Components, as well as member of the European Senior Advisory Group for several research networks.
