Title of Speech: Shape Memory Alloys for Aerospace Applications
Abstract: Shape memory alloys (SMAs) are special class of metallic alloys which have the ability to recover from their original shape at some characteristic temperatures (it is called the shape memory effect), even under high loading and large inelastic deformations. Also, they can undergo large strains without plastic deformation or failure exhibiting super-elasticity. Thus they offer several advantages that the product designers can exploit such as the possibility of transmitting large forces and deformations, compactness, and the intrinsic capability to absorb loads. In addition, in some applications their use as monolithic actuators can lead to potential simplifications of the system through a reduction of number of parts and the removal of other redundant mechanisms. For these reasons, in past couple of decades the aerospace industry has paid increasing attention on using SMAs, even though issues regarding their fatigue life and performance degradation need to be addressed. In this keynote review paper, we describe the main features of SMAs, their constitutive models and their properties. We also review the fatigue behavior of SMAs and some methods adopted to remove or reduce its undesirable effects. The review includes examples of applications of SMAs in fighter aircraft, transport aircraft, rotorcraft, UAV and spacecraft.
