DESCRIPTION:Adhesive joints offer several advantages over traditional join
 ts (welds\, rivets)\, including reduced weight\, excellent surface finish 
 and the ability to bond dissimilar materials (i.e. metal to polymer).  Adh
 esive technology is particularly relevant to applications incorporating li
 ghtweight materials such as composites and aluminium\, which are of increa
 sing interest in the transportation industry. Adhesives are finding applic
 ations in the naval industry\, but adoption is limited by an incomplete un
 derstanding of the mechanics of adhesive joints. How do failure strength\,
  toughness and damage tolerance vary with the thickness of an adhesive lay
 er? Can these properties be improved\, or varied to meet specific design r
 equirements? To address these questions\, a variety of quasi-static tests 
 have been conducted on adhesive joints composed of aluminium and a rubber-
 like MS-polymer adhesive. Butt joints and double-lap shear joints were stu
 died and the observed failure mechanisms are discussed. Joints with novel 
 interface geometries\, such as “square wave” periodic interlocking int
 erfaces\, have also been studied. A design tool has been developed which p
 redicts the peak strength and work of fracture of square wave interfaces a
 s functions of geometric parameters. A performance map is presented\, whic
 h can be used to guide the design of future interfaces according to design
  requirements.
