Abstract
A review of the investigations that have been made on the stress and s trength analysis of mechanically fastened joints in fibre-reinforced p lastics (FRP) is presented. The experimental observations of the effec ts of joint geometry, ply-orientation, lay up and through-thickness pr essure on the joint behaviour are described briefly for both single an d multi-fastener joints. The analytical and numerical methods of stres s analysis required before trying to predict failure are discussed. Th e numerical approaches cover both two and three-dimensional models and the effects of clearance, friction and geometry are assessed. The sev eral methods that have been used to predict failure in single or multi -fastener joints are described. It is concluded that there are some is sues that require further investigation. There is no general agreement about the method that should be used to predict failure, but progress ive damage models are quite promising since important aspects of the j oint's behaviour can be modelled using this approach. In order to take into consideration several factors related to joint strength the use of three-dimensional models is suggested. These models require a three -dimensional failure criterion and an appropriate property degradation law. (C) 1997 Elsevier Science Limited.
