Effects of non-uniform strains on tensile fracture of fiber-reinforced ceramic–matrix composites have not been satisfactorily explained by existing mechanics-based models. In this paper, we use an exact model of fiber fragmentation under global load sharin ...
Ultra High-Performance Fibre-Reinforced Concrete (UHPFRC) combines high strength, deformation capacity and low permeability. This makes UHPFRC particularly suitable as a strengthening and protective layer for application to existing reinforced concrete str ...
Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...
Strain Hardening Ultra High Performance Fiber Reinforced Concrete (SH-UHPFRC) were used successfully over the last 8 years in numerous cast in place rehabilitation applications as long lasting waterproofing layers (20 to 30 mm thickness) and, combined with ...
The resistance as well as strain hardening and softening properties of UHPFRC depend on the type of matrix and mainly on the fibre dosage and final distribution and orientation in the element. The strength and deformability distribution in a thin UHPFRC pa ...

Trigonoliimine B, a hexacyclic alkaloid, is synthesized in seven steps from simple starting materials. The synthesis features the use of an alpha-isocyanoacetate as a glycine template for the preparation of an alpha,alpha-disubstituted alpha-amino ester th ...
The addition of a thin overlay of reinforced UHPFRC (R-UHPFRC) to a reinforced concrete (RC) element creates a composite member which can be used for the strengthening of an existing structure and in the design of new structures. With its strain hardening ...
High Performance Cement-based composites such as some UHPFRC or SHCC exhibit a tensile strain hardening response associated to the progressive formation of finely distributed microcracks. Strain Hardening (SH) - UHPFRC with suitable fibrous mixes have a de ...
We extend the analysis of Hutchinson and Neale (Hutchinson JW, Neale KW. Acta Metall 1977;25:839) and Ghosh (Ghosh AK. Acta Metall 1977;25:1413) predicting the tensile elongation to failure of strain-rate-dependent plastic materials to two-phase composites ...
