“…The effect of annealing on its law should be studied in depth from several angles, such as the fatigue life of SMAs. (7) The cost-effectiveness of SMA reinforcement techniques cannot be analyzed only from a static point of view, such as material costs and construction costs. They should also be analyzed in terms of life-cycle costs, taking into account the long-term performance, environmental impact, and structural performance and safety.…”

The utilization of shape memory alloys (SMAs) to reinforce steel structures has been proven to be an efficient and reliable method, the structural strengthening needs can be met without the need for tensioning equipment by activating the SMAs to generate restoring stresses. This paper firstly introduces the properties of SMA, and then presents the latest research progress, opportunities and challenges of SMA in the field of steel structural reinforcement, both in terms of basic components and applications. In terms of components, the construction forms and working mechanisms of Fe-SMA strips, SMA/CFRP composite patches and SMA dampers are introduced. On this basis, the application of SMA in steel structures reinforcement is introduced, and its effect is analyzed from three aspects: crack restoration, seismic retrofitting and structural strengthening. Finally, the results of the current research are summarized and the shortcomings are analyzed, hoping to provide a reference for the research of SMA in the field of steel structures reinforcement.

“…The developed model was then validated experimentally considering tip deflection–time response under variation of voltage. Liu et al (2018) theoretically studied a novel adaptive jet engine chevron concept based upon embedding functionally graded SMA actuators in a composite laminate. The constitutive models of the functionally graded SMA actuator composites include the monolayer SMA composites.…”

A new model is proposed to describe the response of laminated composite beams consisting of one shape memory alloy layer and one functionally graded material layer. The model accounts for asymmetry in tension and compression of the shape memory alloy behavior and successfully describes the dependence of the position of the neutral surface on phase transformation within the shape memory alloy and on the load direction. Moreover, the model is capable of describing the response of the composite beam to both loading and unloading cases. In particular, the derivation of the equations governing the behavior of the beam during unloading is presented for the first time. The effect of the functionally graded material gradient index and of temperature on the neutral axis deviation and on the overall behavior of the beam is also discussed. The results obtained using the model are shown to fit three-dimensional finite element simulations of the same beam.

“…In the last two decades, a new class of materials known as FG-SMA has the material properties combining the advantages of functional gradient material and shape memory alloy material, which not only has the phase transformation property of SMA, but also has the material property varying gradually as the position changing of functional gradient material [1][2][3][4]. Moreover, there is no stress concentration when two materials are combined, which makes FG-SMA with a promising application prospect.…”

Bending is an attractive mode of operation and application of functionally graded shape memory alloy (FG-SMA). For decades, numerical methods, such as the finite element method, have been used to model the mechanical behavior of these alloys. In this paper, combining with the critical stress-temperature relationship and stress-strain relationship of shape memory alloy, it researched the mechanical behavior of FG-SMA beam under thermal and mechanical loads with the macroscopic constitutive model. The split-step method was adopted to analyze the process of FG-SMA phase transformation in the loading process. The relationship between stress distribution and three factors that included tension-compression asymmetry coefficient, temperature and power exponent were obtained, and the nonlinear controlling equations of FG-SMA beam were acquired. The influence of tension-compression asymmetry coefficient, temperature and power exponent on deflection, curvature and cross section stress, neutral axis and phase boundary were obtained by solving the equations. It was found that the phase transformation of FG-SMA beam became more and more difficult as the increase in temperature and power exponent. Furthermore, the tension-compression asymmetry coefficient had a great influence on the compression side phase boundary, but it had a little influence on the tension side phase boundary.
