“…The textile composites with a smart SMA-Base seems to be quite promising since the tremendous diversity of textile architecture allows the SMA components to easily fabricate their various forms. For example, SMA wires or yarns can be used as "smart fibers" combined with conventional glass/carbon fibers so as to make a part of the textile perform multi-functional properties [8]. Although SMA textile composites are able to control the actuator function by careful designing the shapes of SMA textile, it is difficult for the processing of SMAs into textile structures with special shapes.…”

Shape memory alloys (SMAs) possess both sensing and actuating functions due to their shape memory effect, pseudo-elasticity, high damping capability and other remarkable properties. Combining the SMAs with other materials can create intelligent or smart composites by utilizing the unique properties of SMAs. In this paper, epoxy resin composites filled with NiTi alloy short fibers and particles were fabricated and their mechanical properties investigated. Owing to the addition of SMA fillers, the flexural rigidity of SMA/epoxy composites increases. Especially, the storage modulus increases remarkably with increasing filler content in the high temperature region. The experimental results show that the addition of just 3.5% of SMA fillers to epoxy resin resulted in a remarkable increment of storage modulus, which is six times as large as that of epoxy bulk (ER3). The storage modulus reaches the maximum at the SMA phase transformation temperature of approximate 120 o C. The loss factor of SMA/ER3 composites increases with the increment of SMA filler contents. Based on the Halpin-Tsai theory, moreover, a model for the laminated plates with SMA fillers is presented to predict the dynamic mechanical properties. Compared to the experimental results, reasonable prediction of the dynamic behavior is obtained based on the present models.

“…Thompson and Loughlan's extensive experimental and numerical simulations [22,23] indicate that recovery forces in pre-strained SMA fibers produced by thermal activation enhance the buckling temperature for various laminated plates and reduce the out-ofplane displacement of the post-buckled laminates. More recently, Zhang et al [24] studied vibration of laminated composite plates with embedded SMAs by using the Rayleigh-Ritz method. In the aforementioned investigations, the SMA fiberreinforced composite structures are either beams or rectangular plates.…”

Axisymmetric deformations of a uniformly heated pre-buckled and post-buckled thin circular plate reinforced with shape memory alloy (SMA) fibers placed in the radial direction only are studied. Effects of von Kármán's nonlinearities are incorporated in the problem formulation. The matrix is assumed to be linear thermoelastic and the thermo-mechanical response of the SMA is modeled by one-dimensional constitutive relation. By assuming that plate's deflections can be additively decomposed into three parts, namely radial displacements of a pre-buckled plate, radial and lateral displacements during post-buckling deformations, and infinitesimal radial and lateral displacements during vibration of a post-buckled plate, boundary-value problems for determining these displacements for plate edges either simply supported or clamped have been formulated. The coupled nonlinear differential equations have been numerically solved by the shooting method that has been verified by good agreement between the presently computed results with those available in the literature. The dependence of the first three frequencies upon the temperature rise, for both pre-buckled and postbuckled plates, has been delineated. Characteristic curves relating the frequency with the temperature rise for different values of the volume fraction and the pre-strain in the SMA fibers are exhibited. It is found that reinforcement of an aluminum plate with SMA fibers changes plate's natural frequencies and enhances its resistance to buckling due to temperature rise.

“…The results depicted that SMA fibres have significant influence on increasing the critical buckling temperature. Zhang et al (2006) explored the vibrational characteristics of a laminated composite plate containing unidirectional fine SMA wires and laminated composite plates with embedded woven SMA layer experimentally and theoretically. They showed the influence of both SMA arrangement and temperature on the vibrational characteristics.…”

In the present study, an analytical closed form solution for free vibration response of hybrid composite plate reinforced with shape memory alloy (SMA) fibers is derived. Recovery stresses generated during martensitic phase transformation are obtained based on onedimensional Brinson's model. The mechanical properties of plate are assumed to be temperature dependent. Based on the first-order shear deformation theory (FSDT) the governing equations are obtained via Hamilton's principle. Ritz method is used to obtain the fundamental natural frequency of the plate for different temperatures. A detailed parametric analysis shows the strong influence of the volume fraction, pre-strain, orientation and location of SMA fibers as well as the aspect ratio of the plate on the fundamental natural frequency and the onset of the thermal buckling.
