“…Vibration control techniques employing SMAs are reported in the literature for general vibration problems (Aguiar et al, 2013; Enemark et al, 2015; Gandhi and Chapuis, 2002; Lee and Pai, 2015; Mani and Senthilkumar, 2015; Mishra et al, 2013; Rezaei Da et al, 2012; Savi et al, 2011), including the vibration response enhancement of civil structures (Alam et al, 2007; Auricchio et al, 2006; Cismaiu and Santos, 2008; Huang et al, 2014; Ibrahim, 2008; Janke, 2005; Kuang and Ou, 2008; Mani and Senthilkumar, 2015; Ozbulut et al, 2011; Sun and Lv, 2015; Torra et al, 2007; Wang and Wu, 2012; Zuo and Li, 2011) as well as aerospace structures (Bachmann et al, 2012; Barzegari et al, 2012, 2015; Sousa and De Marqui, 2016; Ibrahim, 2008; Korkmaz, 2011; Tawfik et al, 2002; Yun et al, 2006).

An experimental study on the aeroelastic behavior of a 2-degree-of-freedom typical airfoil section with superelastic shape memory alloy springs is reported. Shape memory alloy helical springs are included in the pitch degree-of-freedom of the typical section so that the effects of pseudoelastic hysteresis on the aeroelastic behavior of the system can be investigated. The experimental identification of the aeroelastic parameters is described. Wind tunnel tests are conducted for different shape memory alloy springs’ preload levels, airflow speeds, and initial conditions. It is shown that the linear unstable post-flutter behavior is transformed into stable limit cycle oscillations of acceptable amplitudes over a range of airflow speeds due to pseudoelastic hysteresis. Therefore, shape memory alloy springs can be effectively exploited to passively enhance the aeroelastic behavior of a typical section.

This study explores the experimental response and failure behavior of an SMA cable brace. The kernel of the developed SMA brace consists of four SMA cables with a diameter of 8 mm. The cables are configured within bracing system in a way that they are only subjected to tensile loads regardless of the loading direction of the bracing itself. A mechanical anchorage system that can satisfactorily anchor SMA cables of the bracing system was first described, and its performance was validated. Then, the design and fabrication process of the SMA brace was discussed. Two SMA cable braces were manufactured and tested under different loading conditions. The first SMA brace was subjected to increasing displacement amplitude loading protocol until all SMA cables within the bracing system failed. The evolution of various parameters such as equivalent viscous damping and residual deformations with the displacement loading amplitude was quantitatively evaluated. The second SMA brace was tested for consistency verification and to study the effects of loading frequency and number of loading cycles on the response of the SMA brace. Results obtained from the experimental tests revealed the excellent self-centering behavior of SMA brace with an ultimate force capacity of 125 kN and a displacement capacity of 65 mm. The equivalent viscous damping for the developed brace was about 5%. The complete failure of the brace was gradual, and the SMA brace was able to carry large loads even after one or two SMA cables ruptured.

“…Pioneering SMAs researches associated with solid mechanics and material science have proposed in-depth theory and different receipt for optimizing the effects of strain and strain relief [12,13]. Smart materials such as SMAs and SMAF efficiently convert thermal energy into mechanical deformation, and the phase transformation results in (a) SME and (b) pseudoelasticity [14,15]. Thermocouple, strain gauge, and extensometer are well-developed sensors, and both give additional mass and force to the sample under the measurement of temperature and strain [16].…”

Fibers made from shape memory alloys perform strain recovery during phase transformation of crystal structure. Controlled parameters such as heating time, holding temperature, and cooling time dominate the micro deformation of shape memory alloy fiber (SMAF). Mechanical contraction occurs at high temperature (austenitic phase), and strain-relief happens at low temperature (martensitic phase). But the rapid change of temperature causes unfinished or incomplete phase transformation, which induces residual strain within the SMAF. The accumulated defects shorten the specimen's life during cyclic loading and lower the limit of fatigue failure. This study uses digital image correlation to provide the in-situ response temperature-strain relations during the phase transformation and quantizes the residual strain within the SMAF. Experiments accurately control the holding temperature of SMAF in three conditions, which are (a) under, (b) around, and (c) beyond the phase transformation temperature of the specimen, and systematically analyzes the self-accommodation and strain-recovery of SMAF in the three experiments. The in-situ measurement of microscale deformation can help the end-user optimize the control parameters and increase the life and performance of SMAF.
