|Summary||The essential difficulties to assess the performance of composite material structures lies in the fact that various kinds of mechanical,geometrical and material inhomogeneity should be taken into consideration in every phase of analysis,ranging from fiber/matrix interfaces to adhesive joints of structural components.However the recent advances in experimental and computational mechanics have been making it possible to offer more flexible and versatile techniques,ranging from micro (or meso)-mechanics to macro-mechanics,for more realistic and accurate modeling of composite material structures,not only for structural performance but also for damage growth process.Several typical and successful applications of these approaches are illustrated and discussed with special reference to characterization of damage and damage progression including some emerging new fields such as health monitoring techniques of composite material structures.
