plastic shear occurs appears rather uncertain and depends on the relative properties
of the fiber and matrix components and the bonding at the interface. Nevertheless, if
large scale fragmentation of brittle matrix is accompanied by plastic bending of the
fiber, substantial amounts of energy would be required under these circumstances
(Williams et al., 1973).
