“…In the present work, the original plasticity model was adopted and modified to account for the changes in the characteristic compressive behaviour that occur with the addition of fibres, in particular steel fibres. Experiments on steel fibre reinforced concrete specimens subjected to uniaxial compression [15,44] indicate several characteristic features such as:…”

“…To reflect this, c c2 is assumed to have the following nonlinear variation with respect to the volume fractions of fibres V f : It is further assumed that the compressive strength (f c ) and the strain at peak stress (ε c ) in Eq. (29) are functions of fibre content and aspect ratio [15,44] …”

“…A number of macroscopic models have been proposed for simulating the compressive behaviour of FRCs; Bencardino et al [11] provides a review of four empirical models for the stressstrain behaviour of steel fibre-reinforced concrete in compression [12][13][14][15] and compares their performance against several sets of experimental data. The study concludes that each of the models studied agrees well with the experimental data from which the model relations were derived but that the models do not show the same level of agreement when compared with other experimental data.…”

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.

“…The increase percentages in static modulus of elasticity for these uses were found to be 33% and 42%, respectively. This is probably due to the optimization of these percentages of fibers to operate the higher bond strength behavior and thus a higher modulus of elasticity [22].…”

The production and use of durable materials in construction are considered as one of the most challenging things for the professional engineers. Therefore, this research was conducted to investigate the mechanical properties and the durability by using of different percentages of steel fiber with high-strength flowable mortar (HSFM) and also the use of the hybridization of steel fibers, palm fibers, and synthetic fiber (Barchip). Different experimental tests (compressive strength, splitting tensile strength, flexural strength, and static modulus of elasticity among others) were determined after 90 days of normal water curing and 180 days of seawater exposure. The results indicate that hybrid fibers of 1.5% steel fibers + 0.25% palm fibers + 0.25% Barchip fibers provide significant improvement in the different mechanical properties of HSFM. Besides, the hybridization of fibers was found to be effective in the terms of durability (exposure to seawater). Therefore, the minimum reduction in static modulus of elasticity, compressive, splitting and flexural strength was obtained for the HSFM mixes of hybrid fibers using steel fibers with palm fibers and also for the use of steel, palm, and Barchip fibers.

“…Most of the previous experiments as well as formulations have been limited to uniaxial tension ͑Li et al 1998; Nataraja et al 1999;Ramesh et al 2003͒. Such knowledge, however, is insufficient for structural design in general.…”

Microplane Model M5f for Multiaxial Behavior and Fracture of Fiber-Reinforced Concrete

et al. 2007

Despite impressive advances, the existing constitutive and fracture models for fiber-reinforced concrete ͑FRC͒ are essentially limited to uniaxial loading. The microplane modeling approach, which has already been successful for concrete, rock, clay, sand, and foam, is shown capable of describing the nonlinear hardening-softening behavior and fracturing of FRC under not only uniaxial but also general multiaxial loading. The present work generalizes model M5 for concrete without fibers, the distinguishing feature of which is a series coupling of kinematically and statically constrained microplane systems. This feature allows simulating the evolution of dense narrow cracks of many orientations into wide cracks of one distinct orientation. The crack opening on a statically constrained microplane is used to determine the resistance of fibers normal to the microplane. An effective iterative algorithm suitable for each loading step of finite element analysis is developed, and a simple sequential procedure for identifying the model parameters from test data is formulated. The model allows a close match of published test data on uniaxial and multiaxial stress-strain curves, and on multiaxial failure envelopes.
