“…The DME response of FePd [322] and CME of NiFeGaCo [459] were also investigated and in the latter case it was reported that an electric field applied to the piezoelectric layer could control the corresponding CME. Furthermore, in the case of MnNiSn/PMN-PT laminate, it was noted that the electric bias had a strong effect on the CME was observed and, importantly, magnetization reversal was observed without a bias field [463]. Similar effects have been explored for power generation and energy harvesting.…”

“…Finally, depending on the geometry, convective boundary conditions and associated heat transfer, the latent heat of transformation may have a strong impact on the deformation response and the stress-strain hysteresis loop area of SMAs as shown experimentally in [364] and is also responsible for apparent rate dependencies [400]. As such, the thermal response of SMAs in different configurations has been extensively investigated [288,298,463].…”

Following their discovery in the early 60's, there has been a continuous quest for ways to take advantage of the extraordinary properties of shape memory alloys (SMAs). These intermetallic alloys can be extremely compliant while retaining the strength of metals and can convert thermal energy to mechanical work. The unique properties of SMAs result from a reversible difussionless solid-to-solid phase transformation from austenite to martensite. The integration of SMAs into composite structures has resulted in many benefits, which include actuation, vibration control, damping, sensing, and selfhealing. However, despite substantial research in this area, a comparable adoption of SMA composites by industry has not yet been realized. This discrepancy between academic research and commercial interest is largely associated with the material complexity that includes strong thermomechanical coupling, large inelastic deformations, and variable thermoelastic properties. Nonetheless, as SMAs are becoming increasingly accepted in engineering applications, a similar trend for SMA composites is expected in aerospace, automotive, and energy conversion and storage related applications. In an effort to aid in this endeavor, a comprehensive overview of advances with regard to SMA composites and devices utilizing them is pursued in this paper. Emphasis is placed on identifying the characteristic responses and properties of these material systems as well as on comparing the various modeling methodologies for describing their response. Furthermore, the paper concludes with a discussion of future research efforts that may have the greatest impact on promoting the development of SMA composites and their implementation in multifunctional structures.

“…The former corresponds to C j1 = 0 and the latter corresponds to C j2 = 0. Different boundary conditions lead to totally different thermo-mechanical coupling and should be carefully addressed in practice [28,29]. For simplicity, in the next numerical analysis, the latter is used with C 12 = C 22 = 0, C 11 = C 21 = 1.…”

A thermoelastic solution for the functionally graded rotating thick-walled tube subjected to axisymmetric mechanical and thermal loads is given in terms of volume fractions of constituents. We assume that the tube consists of two linear elastic constituents and the volume fraction of one phase is a power function varied in the radial direction. By using the assumption of a uniform strain field within the representative volume element, the theoretical solutions of the displacement and the stresses are presented. Based on the relation of the volume average stresses of constituents and the macroscopic stresses of the composite material in micromechanics, the present method can avoid the assumption of the distribution regularities of unknown overall material parameters appeared in existing papers, such as Young's modulus, thermal expansion coefficient, thermal conductivity, and density. The effects of the angular velocity, the volume fraction, the ratio of two thermal expansion coefficients, the ratio of two thermal conductivities, and the ratio of two densities on the displacement and stresses are systematically studied, which should help structural engineers and material scientists optimally design thick-walled tube comprised inhomogeneous materials.
