NiTi SMA wires were embedded in the composite laminate beyond the neutral layer, and by electric current, they are heated up to produce the large recovery force. Consequently, the bending deformation of SMA reinforced structure is achieved. Due to the nonlinear behavior of SMA and the complexity of the principles of stress, strain and shape of the composite structure embedded with SMA wires, use the artificial neural network to establish the model of steady-state deflection-intensity of electric current. Eventually, the relative error between the expected date of the model and the experimental data is less than 9%.
