摘要
A comprehensive parametric study on the pullout behavior of a cylindrical model has been carried out using finite element analysis. Interfacial slip-stick phenomena were included in the analysis of a short debond length range. The effects of such important parameters as thermal expansion mismatches between fiber and matrix, fiber volume fraction, material properties of fiber and matrix, and the coefficient of friction at the debond interface, on the debond tip energy release rate, G(i), and fiber-matrix relative displacement, u, were determined. Effects of these parameters on the applied fiber stress-displacement relation were discussed quantitatively. The results of Hutchinson and Jensen and the present results were compared to understand the accuracy of the shear-lag based analytical results.
