Descripción
A promising field for the application of UHPFRC is the construction of protective structures against impact or explosive loading, where energy absorption requires high absorption capacities. For that reason, it is necessary to understand materials response under dynamic loading. The strain-rate dependence of UHPFRC comes from the different mechanisms mobilized during the pull-out of the fibers from the matrix. In this paper, an analytical methodology is proposed to understand the interaction among such mechanisms for smooth and hooked steel fibers. Bond between fibers and matrix, friction, local damage of the matrix and fiber plastification are considered in the analysis. The proposed methodology can be useful in the design of UHPFRC materials able to develop a pseudo-ductile failure mode thanks to the pull-out of the fibers before the possible occurrence of a more brittle failure due to fiber rupture under highly-dynamic loading.
