| Abstract: | The paper describes use of self-consistent finite element method (SCFEM) for predicting effective properties of fiber composite
with partially debonded interface. The effective longitudinal Young's modulus and shear modulus for unidirectional fiber reinforced
composites with fiber-end cracks are calculated. Numerical results show that the effective properties are considerably influenced
by the fiber-end cracks. The effects of microstructural parameters, such as fiber volume fraction, modulus ratio of the constituents
and fiber aspect, on the effective properties of the composites were discussed.
