Abstract: Abstract Fiber reinforcement of ultra-high-performance concrete (UHPC) is necessary for adding toughness and ductility to an otherwise very brittle matrix. The action of fibers pulling out of the concrete matrix is one of the primary… read more here.

DOI: 10.1016/j.compositesb.2018.12.116
Abstract: Abstract The properties of nanoscale interphase significantly influence the mechanics of load transfer and hence the macroscopic behavior of fiber-reinforced composites. Herein, we present a theoretical framework to study the mechanics of stress transfer through… read more here.

DOI: 10.1016/j.compstruct.2017.04.064
Abstract: Abstract This study investigated the effects of fiber type and matrix strength on the fiber pullout behavior of high-performance fiber-reinforced cementitious composites (HPFRCC). The correlation between single fiber pullout behavior and flexural behavior of HPFRCC… read more here.
