Abstract

The paper deals with applications of fibre processes in the plane. The problem of simulation of curved fibre systems with given marginal distributions of orientation, curvature and length is studied. An algorithm is proposed and the geometrical properties of the simulated fibres studied. This problem arose in fractography when observing electron micrographs of fatigue crack surfaces. These images are modelled by thick fibres and quantified. The aim is to find geometrical parameters which correlate with crack velocity. Some results in this direction are presented using the data from fatigue tests.
