| description | In this study, an experimental investigation was conducted to assess the flexural
tensile strength and crack-closing performance of mortar beams containing short shape
memory alloy (SMA) fibers, randomly distributed only on the tensile side. The SMA
fibers were mainly composed of titanium (Ti), nickel (Ni), and niobium (Nb). In
addition, the effect of tensile steel wires on the flexural strength and
crack-closing performance was evaluated. A four-point bending test was performed to
evaluate the post-cracking tensile strength. This study also suggested a proper model
to calculate the ultimate flexural moment of the SMA fiber–embedded beams.
Subsequently, a heating plate that could be installed at the bottom of the beam was
used to induce the shape memory effect and measure the closed crack width. This study
assessed the crack-closing performance induced by the SMA fibers at the bottom side
of the beams and the resistance of the tensile wires in the beams. |
