The Impact

This paper investigates the method to improve the property that can decrease the impact response of composite plate. Embedding the super-elastic shape memory alloy wires into composite plates has increased the attention of material researchers. Super-elastic shape memory alloy has the properties of absorbing mechanical energy, large recoverable deformation and so on. In this study, experiments were conducted to analyze the impact properties of composite plates with Ni-Ti SMA wires. Composite plates with Ni-Ti SMA wires and without Ni-Ti SMA wires were subjected to two impacts respectively. This study measured the responses of two impacts. The results showed that the composite plate with Ni-Ti SMA wires were subjected to a second impact with a peak deflection of 5.47 mm, which was only 0.22 mm larger than the first impact. The relevant data of the composite plate without Ni-Ti SMA wires were 9.02 mm, 1.22 mm, and serious damage occurred. It was verified that the Ni-Ti SMA wires improved the impact resistance of the composite plate. After studying the impact tests of variable diameters of SMA wires embedded at the low layer of composite plate, it was shown that as the diameter of SMA wires increased, the impact resistance of composite plates was improved.

Pull Out

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.
