摘要: This study deals with modelling and characterization of damage due to impact loading in adhesively bonded structures with composite adherends. The presence of joints in a component makes damage characterization, failure predictions and non destructive testing more difficult than for a component without joints. Joints serve as regions of localized high stresses. Especially in case of mechanical fasting (eg using rivets or bolts) this is more true because of the geometric and material discontinuities that they introduce. In particular composites are not very suitable for mechanical fastening because the polymeric matrix unlike metals does not yield locally under the bolts. Hence this results in high stress concentrations around the bolts. This particular problem can be avoided by the use of adhesive joints. However in practice adhesive joints find limited application in safety critical components due to the difficulty in …
