“…How to consider the substrate material and SMA discontinuities during modeling, as well as the stress and displacement transfer between the material interface at the micro level [14,15]. Secondly, SMAs have unique pre-strain properties and martensite austenite transformation properties [16][17][18], which not only help to improve the overall stiffness and dynamic properties of composite plates but also offer a fresh approach to designing and managing their vibration and acoustic radiation properties [19,20].…”

The constitutive model and modulus parameter equivalence of shape memory alloy composites (SMAC) serve as the foundation for the structural dynamic modeling of composite materials, which has a direct impact on the dynamic characteristics and modeling accuracy of SMAC. This article proposes a homogenization method for SMA composites considering interfacial phases, models the interface stress transfer of three-phase cylinders physically, and derives the axial and shear stresses of SMA fiber phase, interfacial phase, and matrix phase mathematically. The homogenization method and stress expression were then used to determine the macroscopic effective modulus of SMAC as well as the stress characteristics of the fiber phase and interface phase of SMA. The findings demonstrate the significance of volume fraction and tensile pre-strain in stress transfer between the fiber phase and interface phase at high temperatures. The maximum axial stress in the fiber phase is 705.05 MPa when the SMA is fully austenitic and the pre-strain increases to 5%. At 10% volume fraction of SMA, the fiber phase’s maximum axial stress can reach 1000 MPa. Ultimately, an experimental verification of the theoretical calculation method’s accuracy for the effective modulus of SMAC lays the groundwork for the dynamic modeling of SMAC structures.

“…Taheri-Behrooz et al (2011) profoundly presented the design process of an SMA wire-reinforced hybrid composite plate and reported the influence of various parameters including the mechanical behavior of the constituents, the SMA volume fraction, the temperature-dependent loading effects, and the fabrication process on the overall behavior of the composite plate. The same research group conducted a study on the influence of embedding SMA wires on the macroscopic mechanical behavior of glass-epoxy composites using finite element simulations (Taheri-Behrooz and Kiani, 2017). The authors reported that smart structures fabricated using composite layers and prestrained SMA wires demonstrated an overall stiffness reduction at both ambient and elevated temperatures which were increased with increasing SMA volume fraction.…”

A new analytical model is derived for cantilever beams made from superelastic shape memory alloy and subjected to tip load. The deformation of the beam is described based on Timoshenko beam theory using constitutive relations that account for asymmetric shape memory alloy response in tension and compression. Analytical moment and shear force equations are developed and the position of the neutral axis and the different solid phase regions in the beam are tracked throughout a full loading–unloading cycle. Validation of the proposed model is carried out against data from the literature and from the finite element analysis considering tensile–compressive asymmetry in shape memory alloy behavior.

“…These material features are the result of the reversible martensitic phase transformation that occurs between a high symmetry, austenitic phase and a low symmetry, martensitic phase, in response to the thermo-mechanical loading (Lagoudas, 2008). Due to these unique characteristics, there is an increasing number of potentially industrial applications such as robotics (Ho and Desai, 2009; Kheirikhah et al, 2011), automotive (Stoeckel, 1990; Williams and Elahinia, 2008), aerospace (Calkins et al, 2006; Liang et al, 1996; Willey et al, 2001), structural engineering (Ostadrahimi et al, 2015; Peffer et al, 2000; Taheri-Behrooz et al, 2011; Taheri-Behrooz and Kiani, 2017; Wada et al, 2003), and biomedical industries (Mantovani, 2000; Morgan, 2004). One of the most wide applications is embedding SMA wires or particles into a host material to control vibration and damping (Birman, 2008; Sohn et al, 2009), increase stiffness (Daghia et al, 2008), change shape (Baz et al, 2000; Yang et al, 2006) repair damage (Wang, 2002), modify the buckling load (Ostachowicz et al, 2000), and impact properties (Khalili et al, 2007; Meo et al, 2005) of the host materials.…”

Due to the weak interface in shape memory alloy wire–reinforced composites, the influence of interphase on the mechanical properties and stress distribution of hybrid composites is of considerable importance. In this article, a three-cylinder axisymmetric model using a pull-out test is developed to predict stress transfer and interfacial behavior between shape memory alloy wire, interphase, and matrix. In this article, only superelasticity behavior of the shape memory alloy wire is considered. Based on the stress function method and the principle of minimum complementary energy, stress distribution is derived for three different cases in terms of loading and boundary conditions (thermal loading model, intact model, and partially debonded model). Inhomogeneous interphase and different radial and hoop stress components in each phase are considered to achieve deeper physical understanding. Finite element analysis also performed to simulate stress transfer from the wire to the matrix through the interphase. To evaluate the accuracy of this model, the results of the work are compared with the results of the two-cylinder model proposed by Wang et al. and finite element results.
