Abstract
The applied stress required to initiate interfacial debonding (i.e. the initial debond stress) during fiber pull-out was analyzed using an energy-based debonding criterion. It was shown in part VII that the initial debond stress derived from the strength-based debonding criterion is sensitive to the accuracy of modeling. However, the present study shows that the initial debond stress derived from the energy-based debonding criterion is insensitive to the accuracy of modeling. The dependences of the initial debond stress on the material properties (i.e. the embedded fiber length, elastic constants and radial dimensions of the fiber and the matrix, and the interfacial properties) are also compared for these two debonding criteria. ? 1992.
