The Centre of Biostatistics at the University of Limerick invites you to
its final seminar of the academic year.
Some Extreme Value Problems in Metal Fatigue
Clive Anderson (University of Sheffield)
Friday May 8th 2pm, A2002
Fatigue in metals is the deterioration in load-bearing capacity caused
by repeated application of stress, potentially leading to ultimate
failure. An understanding of fatigue is important for the safety and
reliability of many means of transport and other mechanical systems that
we rely on in everyday life. 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.
Extreme values - for example, strengths of the weakest parts of a
component, or sizes of the largest defects - are key quantities. The
talk will describe how fatigue questions give rise to some interesting
problems in statistical extreme value theory, some of which are
accessible by modern inference techniques.
