A new crack bridging model accounting for slip-hardening interfacial shear stress is derived
for randomly oriented discontinuous flexible fibers in cement-based composites, based on a …

This article presents a computationally efficient method for analyzing the performance of
short-fiber reinforcement in cementitious composites. Each fiber is modeled as a discrete …

A theoretical study on the fibre pull-out energy has been carried out for short fibre-reinforced
composites. Two probability density functions were introduced for modelling the fibre-length …

The performance of fiber-reinforced composites is strongly dependent on the
debonding/pullout behavior of the fibers. In cementitious composites, fibers are usually …

When steel fibers are pulled out from a cementitious matrix, the interfacial friction decreases
with sliding distance. The frictional decay is a function of the far-field lateral stress. In this …

In a composite material that uses fibers as reinforcement, the breakage of the matrix is
produced jointly with the separation of the fiber from the matrix. The mechanical behavior of …

Crack propagation in fiber reinforced composites is governed by bridging stresses provided
by fibers along the crack. To predict the behavior of fiber reinforced structural components …

(1) Purpose Under uniaxial tension,'SFRC can sustain tension after full cracking as a result
of the bridging effect of the steel fibers, as shown in Fig. 1. It is necessary to understand the …

抄録 The mechanical properties of steel fiber reinforced concrete subjected to tension and
shear are investigated experimentally and their mathematical models are presented. High …
