FEA and Experimental Studies of Adaptive Composite Materials with SMA Wires
Kanas, K, Lekakou, C, Vrellos, N and Korsunsky, AM (2008) FEA and Experimental Studies of Adaptive Composite Materials with SMA Wires In: World Congress on Engineering 2007, 2007-07-02 - 2007-07-04, London, ENGLAND.
This study comprises finite element simulations and experimental investigations of the shape memory effect due to the presence of SMA (shape memory alloy) wires in composite materials. FEA was performed using ANSYS, where the pre-strain was modeled by equivalent changes in the expansion coefficient of the SMA. Three case-studies were simulated and the predictions were compared with experimental data: (a) the heating of a pre-strained SMA ribbon in epoxy; (b) the heating of a 4-ply 0 degrees/90 degrees/0 degrees/90 degrees fibre composite (without SMA wires), which causes deflection due to the difference in the expansion coefficients of matrix and fibres, and (c) the heating of a 4-ply 0 degrees/90 degrees/0 degrees/90 degrees fibre composite with SMA wires. The latter case sought to investigate the effects of shape memory alloy wires embedded in the matrix/fibre system.
