Debonding at the fibre-matrix interface and yielding of the fibre occurred during the pull-out process. Both Poisson's contraction of the fibre and Coulomb friction of the debonded interface were considered. The debond length, which consists of an elastic zone length and a plastic zone length, was also analysed. When the fibre has a finite embedded length, it was found that necking prior to full pull-out of the fibre was required to optimize the toughening of a brittle matrix due to plastic deformation of the fibres. The essential material properties to achieve this are addressed. ? 1994 Chapman & Hall.journal article10.1007/BF003565252-s2.0-0028499668https://www2.scopus.com/inward/record.uri?eid=2-s2.0-0028499668&doi=10.1007%2fBF00356525&partnerID=40&md5=8b02e642cf985f19b2c83caadc2f695c
