High temperature damage model for carbon-carbon composites
Résumé
A damage model for carbon-carbon orthotropic composite materials is introduced with a special attention to the thermo-mechanical effects. The internal variables of damage are identified from tension-compression tests according to each fiber direction and from shear tests in each orthotropy plane. The influence of the temperature is taken into account from typical experimental stress-strain curves given for different values of the temperature. The finite element model was implemented in ABAQUS R using an implicit time incremental scheme. Finally, a significant numerical simulation of a thermomechanical loading with damage is presented.
