Report on CDM-based damage model

The goal of the project is to develop computational models for prediction of the initiation and growth of damage in composite bolted joints. Two approaches are being investigated. The first is based on a stiffness reduction scheme. The second is based on continuum damage mechanics. In Workpackage 1 (see deliverables D1.2 [1] and D1.3 [2]) a computational model for the prediction of the initiation and growth of damage in composite bolted joints based on the stiffness reduction scheme was developed and presented. The present report describes work performed in Workpackage 2 on developing a continuum damage mechanics model.
