Abstract
The influence of hygrothermal environmental conditions on the load carry ing ability and response of composite structures are investigated via computational simula tion. An integrated computer code is utilized for the simulation of composite structural degradation under loading. Damage initiation, damage growth, fracture progression, and global structural fracture are included in the simulation. Results demonstrate the signifi cance of hygrothermal effects on composite structural response, toughness, and durability.
