Abstract
The elastic stress transfer from the matrix to the fibre is analysed analytically for fibre-reinforced composites when the loading direction is parallel to the fibre axis. The fibres with bonded lateral interfaces and (1) debonded and (2) bonded ends are considered in the present study. For the case of debonded ends, the present solutions contain refinements of the previously derived analytical solutions. For the case of bonded ends, unlike the numerical solutions derived previously, the present analytical solutions are ready to be used for further analyses. The results show that the stress transfer is more effective when the fibre has higher Young's modulus or longer length. Also, compared to the debonded ends case, the stress transfer is more effective and the stress distribution is more uniform when the ends are bonded to the matrix. ? 1989 Chapman and Hall Ltd.
