Effective fiber length

Thus Ay may be predicted from UTS and an effective fiber length representative of the longer population of the fibers, /f. ... 

A comparison for the case where the effective fiber length, L, is reduced by opening both ends of the fiber to allow flow from each end compared to just one end is illustrated in Figure 2.18. Also shown in Figure 2.18 is a comparison of the average bore pressures for the BOE type versus the single open-ended type. 

The shear-lag analysis of fiber-reinforced composites considers that below a certain length, a fiber is no longer effective in supporting the transfer of load from the matrix. There is thus a minimum effective fiber length that can...

The normalized FAS and IFSS are shown in Fig. 4.17. Both the FAS and IFSS distributions are higher for larger values of residual clamping stress, go, (in absolute terms) for a given fiber length. Varying the coefficient of friction, p, would have similar effects on the stress distributions. The predominant effect of differential Poisson contraction between the fiber and matrix is obvious, particularly in Fig. 4.17(b), where the IFSS values at the fiber ends are several-fold the values obtained in the center.
