“…Flow patterns influence fiber orientation in UHPFRC during the fresh state, namely, the fresh-state behavior of the mixture, casting methods, wall effect, mixture pumping, and applied magnetic field (Huang, Gao and Teng, 2021 [45]; Pae et al, 2021 [46]; Zhou and Uchida, 2017 [47]; Švec et al, 2014 [48]). The material mechanical performance can be significantly improved with fiber alignment when the fibers are preferably aligned in the principal stresses (Duque and Graybeal, 2017 [4]; Bastien-Masse, Denarié and Brühwiler, 2016 [49]; Kang and Kim, 2011 [50]).…”

Strain-Hardening Cement-Based Composites (SHCCs) exhibit high toughness and durability, allowing the design of resilient structures. Despite the exceptional properties of SHCC and the current modeling techniques, the widespread use of the composite is limited. One limiting factor is developing and validating analytical models that could be used for optimizing mixes and designing structural elements. Furthermore, the composite mechanical response is complex and depends on several phenomena, such as fiber pullout, fiber orientation and distribution, size effect, fiber content, group effect, embedding length, fiber dimensions, and matrix strength. In this context, this research presents the state-of-the-art on the micro- and mesomechanisms occurring in SHCC during cracking and robust techniques to predict its tensile behavior accounting for such phenomena already proved experimentally. The study is relevant for designers and the scientific community because it presents the gaps for the research groups to develop new investigations for consolidating SHCC, which is a material to produce resilient structures.
