DESCRIPTION:Compliant shell mechanisms are a new class of lightweight stru
 ctures\, comprising discrete shell elements interconnected along hinge-lin
 es. They undergo large changes in overall shape by deforming between\, and
  by articulating about\, these hinge-lines\, and promise to offer novel so
 lutions for reconfigurable structures such as morphing shells and deployab
 le membranes. This seminar will focus on characterising the behaviour of o
 ne type known as a curved corrugated shell.  Despite its simplicity\, it d
 isplays a remarkable range of deformation in the global sense\, including 
 coupling between extension and bending as well as changes in Gaussian curv
 ature.  Locally\, it may be assumed that the shell deforms inextensibly\, 
 in order to permit a tractable framework for capturing the overall kinemat
 ics and for modelling the load-displacement response.  This will be demons
 trated for a variety of deformed shapes and will be validated by finite-el
 ement analysis and experimental methods.
