SUMMARY:Teeth and Dental Materials - Brian Lawn

CONTACT:Anita Clayson
DESCRIPTION:The mechanics of fracture and other damage modes from contact 
 loading in brittle coatings on soft substrates are of special interest bec
 ause of the potential for premature failures in all manner of layered engi
 neering structures.  In this presentation we will focus on one particular 
 topical area — teeth.  This area of research is of interest in fields as
  diverse as dentistry (replacement crowns) and anthropology (adaptation of
  mammalian dentition to diet).  We describe contact damage modes in model 
 dental systems that allow direct experimental observation of the mechanica
 l responses during loading.  Competing fracture and deformation modes will
  be described\, and consideration given to critical loads to initiate thes
 e modes in terms of conventional materials properties and tooth geometry.
