The delamination problem of laminated composite plates is considered. The Frémond's adhesion approach is developed and adapted to the delamination problem considered. A consistent thermodynamical formulation for the damage model is presented and the governing equations are carried out. The relation between the proposed approach and the fracture mechanics theory is emphasized. Furthermore, a regularized model is developed. A numerical procedure based on the finite element method and on the elastic predictor - damage corrector method is proposed. Numerical results carried out tor beams are compared with the analytical solutions. Finally, the problem of drilling a composite laminate is investigated.

Abstract
The delamination problem of laminated composite plates is considered. The Frémond's adhesion approach is developed and adapted to the delamination problem considered. A consistent thermodynamical formulation for the damage model is presented and the governing equations are carried out. The relation between the proposed approach and the fracture mechanics theory is emphasized. Furthermore, a regularized model is developed. A numerical procedure based on the finite element method and on the elastic predictor - damage corrector method is proposed. Numerical results carried out tor beams are compared with the analytical solutions. Finally, the problem of drilling a composite laminate is investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
