Abstract
Failure of a whisker—reinforced metal—matrix composite by decohesion of the fibre—matrix interface is analysed numerically. A cohesive zone model that accounts for decohesion by normal separation as well as by tangential separation is used to model failure at the interface. The composite material containing a periodic array of aligned fibres is represented in terms of a unit cell model analysis. The effect of varying fibre aspect ratio and varying fibre volume fraction is investigated, and the sensitivity of the predictions to mesh refinements is studied.
