fibres; ductile failure in melt-spun synthetics; high-speed breaks in melt-spun synthetics;
granular breaks in solution-spun fibres; axial splits in HM-HT polymer fibres; stake-
and-socket breaks; and three forms in cotton. There are also breaks due to twisting,
bending and lateral pressure. ‘Fatigue’ breaks occur in tension cycling, repeated bending
and twisting, and surface wear. Multiple splitting is the commonest form of failure in
use.
