Predicting the behaviour of structural adhesive bonds under crash stresses requires the use of Finite Element simulation. This makes it possible to optimise structural adhesives for the highest demands, such as those used in automotive body construction. How this is achieved is shown very well by a simple cohesive zone model.

There is a continuous increase in the use of adhesive bonding as a joining method in sectors such as the automotive, aviation and construction industries. Driven by the rising demand for lightweight hybrid structures, structural adhesives play a key role in joining different materials such as steel, aluminium and composites.

One precondition for successful adhesive bonding is the ability to predict the stress and strain conditions of adhesively bonded structures in crash validation procedures with the aid of Finite Element (FE) simulation. For this purpose, adhesive manufacturers provide methods and parameters that allow adhesives to be characterised under crash...
