Original Abstract

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 distributions. The distributions are determined for two alternatives: (A) the fibers centers have completely homogeneous distribution inside the specimen volume and (B) the fibers have increased density in the bulk so that no fiber can protrude from the specimen boundaries. Additionally, we derive the joint probability density function of a random embedded length and inclination angle to the normal of the (crack) plane for those fibers that intersect that plane.
