Illustration of material modeling. (a) A single layer of unidirectional fiber reinforced composite ply with a continuous matrix and dispersed fibers. (b) The equivalent homogeneous, anisotropic composite ply. (c) Determination of the equivalent material properties E 11 and μ 21. (d) Determination of the equivalent material properties E 22, and E 33. (e) Determination of the equivalent in-plane shear modulus G 12. (f) Symmetrically cross-plied composite laminate. (g) A composite laminate containing a through-width delamination.
