Abstract
Multiple cracking in a fiber-reinforced brittle matrix composite under longitudinal tensile loading is investigated within the framework of linear elastic fracture mechanics. A perfect bond is assumed at the interface. Stress intensity factors are presented for different ratios of shear moduli, crack spacings and fiber volume fractions. Stress fields are given for a brittle matrix fiber-reinforced composite, calcium aluminosilicate glass ceramic reinforced with silicon carbide fibers (SiC/CAS). The stress fields are used to predict damage mechanisms in the composite. It is shown that crack interaction effects are significant for crack spacings that are observed in composites with good bonding at the fiber-matrix interface.
