Probabilistic determination of number of fibers bridging a crack in short fiber reinforced composites

Popis výsledku v původním jazyce

This paper derives the probabilistic distribution functions for a random number of fibers that intersect a plane in a composite specimen reinforced by short fibers. Fibers placed and oriented randomly in 3D space bridge matrix cracks with a certain inclination angle and embedded length distribution, respectively. The distribution is determined for two alternatives: (i) when the fiber centers have completely homogeneous distribution inside the specimen volume and, (ii) when the fibers have modified densities of orientations in the vicinity of the specimen boundaries. Additionally, we derive the probability density function of a random embedded length and inclination angle with respect to the (crack) plane for those fibers that intersect that plane.
