The source of unrealistic predictions of damage evolution in textile composites KU Leuven
The modelling of damage evolution in composite materials normally requires two criteria: one is to identify failure in the undamaged material and one is to establish subsequent failure in already damaged material. However, in the materials models based on the continuous damage mechanics approach (CDM) the second criterion is often assumed to be the same as the criterion of failure initiation. The CDM approach with a single criterion is shown to ...
