“…The input parameters in this model are: the characteristic compressive strength, the diameter, the length, the tensile yield strength of the fiber as well as its volume content, the cross section of the structure to be design and the fiber orientation number. A recent study by Luccioni [31] presents an interesting approach based on modified mixture theory to model SFRC. The authors propose to model concrete with an elastoplastic model and the steel fibers as orthotropic elastoplastic inclusions that exhibit debonding and slipping from the matrix.…”

The recent publication of codes for the design of FRC is a major step towards extending the use of the material. An in depth analysis indicates several differences between the constitutive models proposed in the existing codes. In this study, these models are compared and a numerical simulation is performed to evaluate their differences in terms of the structural behavior predicted and measured in an experimental program of RC-FRC elements. The predictions provided by the models fit satisfactorily the experimental results for elements with steel fibers and with plastic fibers

“…Peng and Meyer [17] presented a continuum damage based model for FRC in which the influence of fibres was taken into account phenomenologically by modifying the damage evolution functions to account for the presence of fibres. Luccioni et al [18] proposed a homogenization approach using a modified mixture theory to model steel fibre reinforced concrete (SFRC) as a composite material comprising a concrete matrix and fibres. The concrete matrix is characterised by a plasticity model whereas the steel fibres are modelled as orthotropic elasto-plastic inclusions that can debond and pull-out from the matrix.…”

A unique constitutive model for fibre reinforced concrete (FRC) is presented, which combines a number of mechanics-based sub models for the simulation of directional cracking, rough crack contact and the crack-bridging action of fibres. The model also contains a plasticity component to simulate compressive behaviour. The plasticity component employs a frictional hardening/softening function which considers the variation of compressive strength and strain at peak stress with fibre content. Numerical results from a range of single-point and finite element simulations of experimental tests show that the model captures the characteristic behaviour of conventional fibre reinforced concrete with good accuracy.

“…This paper employs modified mixture theory for orthotropic materials to simulate FRC behavior taking into account the concrete and fibers contribution. Particularly, the anisotropic behavior of fibers and their slippage are modeled in a simplified way [22].…”

“…A simple homogenization approach for SFRC based on a modified mixture theory was proposed by the authors in a previous paper [22]. SFRC is considered a composite material composed of a concrete matrix, which is modeled with an elastoplastic model [23,24], and steel fibers considered orthotropic elastoplastic inclusions that can debond and slip from the matrix.…”
