ANALYSIS OF INTERFACE CRACKS AT A FIBER END 1)

Based on the general solution of the elastic spatial axisymmetric problem, the stress singularities at the tips of the axisymmetric coin and cylindrical interface cracks at a fiber end in short fiber reinforced composites are analyzed and singular stress fields near the tips of the interface cracks are obtained. The results in this paper show that the stress singularities of the axisymmetric coin and cylindrical interface cracks at a fiber end are the same and they coincide with those of the corresponding c...
