Damage prediction in laminated composites with continuum damage mechanics Conference Paper uri icon


  • A finite element model is developed for laminated composite plates experiencing fatigue load induced microstructural damage. Continuum damage mechanics based constitutive relationships, in which the formation of damage with a laminated composite plate is modeled with strain-like internal state variables, are utilized to obtain the weak form of the equilibrium equation. A damage evolutionary relationship for matrix cracking is incorporated into the model to provide the capability to examine the response history of laminated plate structures. Finally, this model is implemented into a finite element computer code and is used to predict the response of a simple laminated plate structure loaded in fatigue.
