In this investigation an elastic stress analysis is carried out a woven steel fiber reinforced thermoplastic cantilever beam loaded uniformly at the upper surface. The composite beam material consists of low density polyethylene as a thermoplastic (LDFE, f.2.12) and woven steel fibers. Granules of the polyethylene are put into the moulds and they are heated up to 160°C by using electrical resis...

When designing steel fiber-reinforced concrete, for example, according to Model Code 2010, the residual flexural strength values must be specified as fundamental properties. It is often difficult establish relationship between and required dosage of fibers depending on type concrete quality. For an estimation presumably necessary fibers, various empirical approaches exist approximate determinat...

The microstructure of deformation-processed metal-metal composites (DMMC) of Mg-Li alloys containing steel reinforcing fibers was characterized to correlate the fiber size to the deformation strain and mechanical properties of the composite material. Micrographs taken using scanning and transmission electron microscopy techniques revealed fiber sizes larger than predicted from the deformation a...

high performance fiber reinforced cementitious composite (hpfrcc) materials exhibit strain hardening behavior with multiple cracking under tensile loading. in this paper, experimental and parametric studies are performed to assess the influence of using hpfrcc material instead of normal concrete in reinforced concrete beams. after calibrating the experimental results, the analytical results inc...

This study investigates the possibility of replacing minimum web reinforcement in deep beams with discrete fibers. Additionally, equivalent dosage fibers required to obtain similar performance beam is investigated. Deep made plain concrete no fibers, as per AASHTO LFRD recommendations (0.3% both horizontal and vertical), a 0.5% volume fraction steel, macro-synthetic hybrid are tested at shear s...

Concrete filled steel tube (CFST) columns are being popular in civil engineering due to their superior structural characteristics. This paper investigates enhancement axial behavior of CFST by adding fibers plain concrete that infill tubes. Four specimens were prepared: two square (100*100 mm) and circular (100 mm diameter). All 60 cm length. Plain mix reinforced with used columns. Ultimate loa...

In this research, the performance of ultrasonic pulse velocity (UPV) in concrete is examined as a nondestructive experiment in order to estimate mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacted concrete For this purpose 11 mixture designs containing 3 types of fibers (steel: 0.1, 0.2, 0.3 and 0.4 percent by volume, Pol...

Abstract The main aim of the article is to analyze state art in short steel fiber-reinforced geopolymers, taking into consideration also waste fibers. Steel fibers are currently most widely applied additive composites building industry. work dedicated usage and mechanical properties geopolymer composites. Research methods a critical analysis literature sources, including comparison new material...

The simulation of damage and failure in short fiber reinforced composites like high performance hybrid-fiber reinforced cement composites is still a challenging task, due to the richness of failure mechanisms introduced by fibers on the mesoscale of the material. Randomly oriented, hooked steel fibers, like the Baekaert Dramix® fibers, sustainable modify the macroscopic failure behavior of the ...
