Abstract

The increasing use of advanced composite materials in high performance structures has brought a renewed interest in the analysis of materials possessing anisotropy and/or nonhomogeneity. Typically, the application involves filament-reinforced composites stacked in layers to form a laminate. The question of whether the mechanical behavior of such composites can be adequately described by the theory of homogeneous anisotropic elasticity does not possess a general answer. Each situation must be analyzed individually depending on the mechanical properties of the structural elements and construction of the composite system. A comparison between the theory of homogeneous anisotropy and nonhomogeneous isotropy has been made by Sih et al. [1] for the fracture of filament-reinforced composites.
