“…Matrix materials that have been used include polymers [1; 2], metals [3][4][5], plaster [6], and composites such as fiberglass-epoxy [7; 8] and carbon-epoxy [9]. Some applications use the SMA behavior to control the shape of the composite structure [10][11][12], or its vibrational [7; 13; 14] or buckling response [15; 16] while other applications use the SMA components to change the composite's stiffness [7; 17], to strengthen the composite [4], and to close or repair cracks [8; 18-20] Several methods have been developed to study the thermomechanical response for SMA composites, including micromechanical methods [18; 21] and finite element analysis [15; 22; 23]. In some cases, special composite elements have been created to study multi-layered composite plates [24][25][26] and layered beams [27].…”

The usage of shape memory materials has extended rapidly to many fields, including medical devices, actuators, composites, structures and MEMS devices. For these various applications, shape memory alloys (SMAs) are available in various forms: bulk, wire, ribbon, thin film, and porous. In this work, the focus is on SMA hybrid composites with adaptive-stiffening or morphing functions. These composites are created by using SMA ribbons or wires embedded in a polymeric based composite panel/beam. Adaptive stiffening or morphing is activated via selective resistance heating or uniform thermal loads. To simulate the thermomechanical behavior of these composites, a SMA model was implemented using ABAQUS' user element interface and finite element simulations of the systems were studied. Several examples are presented which show that the implemented model can be a very useful design and simulation tool for SMA hybrid composites.

“…Shape memory alloy can be used in shape control due to its high recovery forces and large displacement (Choi and Lee 1998;Oh et al 2001;Yang et al 2006). In the experimental and analytical studies carried out by Choi and Lee, it was shown that the SMA actuators were able to modify the deformed shape of composite (Oh et al 2001).…”

The present study aims to design an experimental test bench to analyze and control a smart structure system composed of a woven fiberglass laminate plate with shape memory alloy (SMA) actuators instilled on the surface. The aim of this design is to accurately augment the strain of the composite plate. Finite element analysis was employed to model the composite structure and determine the placement of the SMA actuators in order to produce the desired structural response efficiently with minimum power consumption. Due to the nonlinear behavior of the SMA actuator, it will be critical to incorporate a feedback control system that is able to accurately morph the structure by changing the strain of the composite structure. A Proportional-Integral-Derivative (PID) controller was designed to improve its tracking performance. Simulation on the control system showed that the PID controller produced acceptable response and managed to reduce steady state error for different types of input. The PID controller was then implemented in the experimental setup to control the smart composite plate. Results from the experiment illustrates that the smart structure system that has been designed performed effectively and the strain value of the composite structure can be controlled accurately.

“…For active applications, it has been shown that SMA wires can act as internal stress generators in polymer composite systems (Bollas et al, 2007), which induce the SMA activation. Some SMA composites models are developed for structure morphing (Brinson et al, 1997;Oh et al, 2001;Armstrong and Lorentzen, 2001;Chemisky et al, 2009a), or for vibration control (Brinson and Lammering, 1993;Aoki and Shimamoto, 2003;Zhang et al, 2007). Other ones simulate the passive behavior to control some properties of the composite, as stiffness (Boyd and Lagoudas, 1996), hysteresis properties after cycling (Kawai, 2000) or the overall behavior (Cherkaoui et al, 2000).…”

a b s t r a c tCommercial Ni 47 Ti 44 Nb 9 Shape Memory Alloy (SMA) is generally adopted for tightening applications thanks to its wide transformation hysteresis, compared with classical NiTi. Its sensibility to thermo-mechanical treatments allows it to be either martensitic or austenitic in a wide range of temperature, between À60°C and 80°C. A modeling of niobium precipitates effects on Ni 47 Ti 44 Nb 9 SMA behavior is proposed. For this object, a two phase thermo-mechanical model is developed. It describes the global effective behavior of an elastoplastic inclusion (niobium precipitates) embedded within an SMA matrix. The constitutive law developed by Peultier et al. (2006) and improved by Chemisky et al.is adopted to model the matrix shape memory behavior. The elastoplastic constitutive law for inclusion is the one proposed by Wilkins with Simo and Hughes's radial return algorithm. The Mori-Tanaka scale transition scheme is considered for the determination of the effective constitutive equations. Obtained results highlight the effect of niobium precipitates on the thermomechanical behavior of Ni 47 Ti 44 Nb 9 , and particularly on the corresponding hysteresis size. It appears that the niobium plasticity increases this hysteresis size. The developed constitutive law has been implemented in the ABAQUS Ò Finite Element code and considered for the numerical prediction of the tightening pressure in a connection application.
