Original Abstract

The pull-out response of a short fiber from the matrix depends on both the bond between the two materials and the geometry of the fiber. Fibers placed and oriented randomly in 3D space bridge matrix cracks with a certain inclination angle and embedded length distribution, respectively. With a pull-out law available in analytical form, statistics of the fiber force-crack opening diagram can be obtained for a uniformly loaded crack bridge in a short fiber reinforced composite by evaluation of probabilistic integrals. This information is utilized to probabilistically evaluate the crack bridging force by computing the sum of a random number (of bridging fibers) of independent random variables (single fiber responses).
