SUMMARY:Towards a theory of inelastic stability - Jurgen Becque\, Universi

DESCRIPTION:The theory of elastic stability has been a great triumph in st
 ructural engineering and underpins the practical design methodologies of a
  wide range of structural elements and systems. Several important metals\,
  however\, such as aluminium and stainless steel alloys\, only exhibit a v
 ery limited linear elastic range\, display gradual yielding and extensive 
 strain hardening\, and cannot be designed using the design methodologies a
 pplicable to carbon steel. A suitable theory of inelastic stability\, on t
 he other hand\, is still in its infancy\, held back by an almost century-o
 ld theoretical hurdle dubbed the ‘plastic buckling paradox’. We will i
 nvestigate the nature and origins of this paradox\, and propose a solution
  based on a consistent application of plastic flow theory. Some new develo
 pments originating from this break-through\, related to buckling of inelas
 tic plates and columns\, will be presented.
