Inhalt:
| | There has recently been a great interest in the use of cohesive zone models to describe fracture in Fracture Mechanics Analyses. The method has a long history going back to Barenblatt and Dugdale in the 1960's and has been widely used in concrete technology. Its wider application has been limited by computational problems but those have now largely disappeared. Fracture processes may be defined via traction curves within a process zone and these may then be used to predict failure under any loading condition.
The method has been shown to work well for elastic-plastic fracture, dynamic crack growth and modelling damage mechanisms and fibre bridging in composites. Some examples will be given and then used to describe possible use in Finite Element design codes.
