Statistics Seminars: Some Extreme Value Problems in Metal Fatigue
17 March 2006 14:00 in CM107
"Fatigue in metals is the deterioration in load-bearing capability leading to ultimate failure and caused by repeated application of stress. An understanding of fatigue is crucial to safety and reliability in many of the systems fundamental to modern living. Randomness is intrinsic to fatigue: loads, environmental conditions and material quality are all variable, and the fundamental mechanisms of fatigue, the initiation and propagation of cracks, are governed by the internal microstructure of the metal, which is naturally described in stochastic terms. Within stochastic modelling, extreme value ideas are now being recognised as central aids to the understanding and prediction of fatigue properties. The talk will show how fatigue questions are giving rise to some interesting new problems (and tentative answers in some cases) in statistical extreme value theory."
