“…The corresponding stress for IHS-SMAF and IS-SMAF is 353.16 MPa and 428.34 MPa, respectively. Surface treatment with sandpaper enhances the surface characteristics of the SMAF, promoting better interfacial bonding, increased frictional resistance, and improved mechanical interlocking[47].These factors collectively contribute to the observed improvement stress 566.23 and 610.54 Mpa, respectively.…”

This experimental study investigates the effect of superelastic shape memory alloy fibers (SMAF) on the pullout performance of Engineered Cementitious Composite (ECC). Various diameters, forms, and surface treatments of SMAF were examined, including Linear shape (LS-SMAF), indented hook shape (HIS-SMAF), and indented shape (IS-SMAF) with diameters of 0.8 and 1.0 mm. sandpaper polishing technique was used for surface treatment. A constant water-to-cement ratio of 0.60 was used to fabricate ECC. Single-fiber pullout tests, monotonic and cyclic, were conducted on ECC mixtures incorporating various polyvinyl alcohol (PVA) content (1.5% to 2%). Scanning Electron Microscope (SEM) analysis was performed to study the internal structure of ECC. Results showed that treated IS-SMAF demonstrated superior pullout performance. Additionally, IHS-SMAF outperformed LS-SMAF, whereas ECC with higher PVA content showed excellent pullout performance. This study concludes the significance of fiber characteristics and ECC mix composition in enhancing single-fiber pullout performance.

Smart structures can help to resolve many issues related to conventional materials that are being used in different industries. Shape memory alloys (SMAs) are smart materials with better actuation response, vibration damping characteristics, and large strain recovery, making them good candidates due to their high strength and corrosion resistance for various engineering applications. The performance of fiber-reinforced polymer (FRP) composite materials that are replacing many conventional materials due to their good strength, stiffness, and lightweight potential especially in fuel-consuming industries such as aerospace and automotive, can further be improved by impregnation with SMAs. This review discusses the SMA-reinforced FRP composites, leading to shape memory hybrid composite materials, the issues and limitations in composite manufacturing, and their uses in different research arenas including impact and damping applications, seismic protection applications, crack closure applications, shape morphing applications, and self-deployable structures.

“…SMA is a brand-new class of smart material that possesses special qualities like superelasticity, temperature phase transition, and pre-strain. SMAC, which are composed of SMA and matrix materials, can fully exploit the phase transition and reinforcement attributes of SMA to increase the strength and kinetic properties of the composites [8][9][10][11][12]. Currently, there are two primary problems with composite plates using shape memory alloys (SMAs): firstly, the modulus of the SMA and the substrate varies significantly.…”

The constitutive model and modulus parameter equivalence of shape memory alloy composites (SMAC) serve as the foundation for the structural dynamic modeling of composite materials, which has a direct impact on the dynamic characteristics and modeling accuracy of SMAC. This article proposes a homogenization method for SMA composites considering interfacial phases, models the interface stress transfer of three-phase cylinders physically, and derives the axial and shear stresses of SMA fiber phase, interfacial phase, and matrix phase mathematically. The homogenization method and stress expression were then used to determine the macroscopic effective modulus of SMAC as well as the stress characteristics of the fiber phase and interface phase of SMA. The findings demonstrate the significance of volume fraction and tensile pre-strain in stress transfer between the fiber phase and interface phase at high temperatures. The maximum axial stress in the fiber phase is 705.05 MPa when the SMA is fully austenitic and the pre-strain increases to 5%. At 10% volume fraction of SMA, the fiber phase’s maximum axial stress can reach 1000 MPa. Ultimately, an experimental verification of the theoretical calculation method’s accuracy for the effective modulus of SMAC lays the groundwork for the dynamic modeling of SMAC structures.
