Abstract
Radial matrix cracking and interphase failure for transverse loading of a hexagonal array fiber composite are investigated by : 1) modeling the compliant interphase by a layer of radial and circumferential spring elements, 2) adopting a tensile stress criterion for initiation of matrix cracking, and 3) employing a strain-energy density criterion for interphase failure. Stresses on the microlevel have been calculated. Under the assumption that the failure mechanisms follow the periodicity of the composite, two damage configurations have been analyzed, namely, conjugate radial matrix cracks and interphase disbonds forming L-shaped and ⊥-shaped defects.
