论文简介
The transverse strengthening behavior of fiber-reinforced metal matrix composites is numerically investigated on the basis of micromechanics
analysis. Periodic boundary condition is developed and employed in calculations for considering arbitrary loading directions
without changing the configuration of the unit cell. The symmetric boundary condition will be naturally attained if the loading is along
the symmetric directions of the unit cell if any. Effects of the volume fraction and several more general fiber arrangements on the transverse
strengthening of composites are discussed in detail, including single and/or multi-fibers simulations, from which the maps of the
strengthening responses in various directions of the composites are obtained. It is concluded that the effect of fiber volume fraction is
significantly different in various directions, the maximum strengthening of composites does not always occur in 0 and/or 90 directions
whereas the minimum strengthening is always in 45 direction, and the strengthening of composites has a period of 90 which are independent
of fiber arrangements.
