In the present work, laminated composite plates with surface bonded shape memory alloy sheets are modeled and analyzed based on the modified higher-order shear deformation theory. The energy balance equations in conjunction with Brinson's SMA constitutive model are used to formulate the heat transfer governing equations. The static responses as well as dynamic characteristics of the plates are obtained using Ritz solution technique. The plates are subjected to mechanical loads with two types of boundary conditions, simply-supported and cantilevered. A Mathematica code is developed to analyze different plate problems. The time response of the shape memory alloy laminated composite plate is studied. The obtained results are compared to the available studies solved by different theories. Parametric studies are conducted to demonstrate the effect of thickness ratio, aspect ratio, material properties, thermal expansion coefficient, and thickness of shape memory alloy sheet on the transverse deflections, natural frequencies, and response time.

“…Furthermore, due to the diffusion of Ti from TiNi alloys to the interface of composite, another diffused layer about 4 lm was formed in the TiNi fiber next to the interfacial layer. It was confirmed that the atomic ratio of Ti and Ni in TiNi alloy had a great influence on the temperature of martensitic transformation [25]. The decrease of atomic ratio of Ti and Ni in the diffused layer was induced by the diffusion of Ti atom.…”

Review and perspectives: shape memory alloy composite systems

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.
