Leghe a memoria di forma e loro applicazioni aerospaziali

This thesis aims to examine SMART materials, in particular shape memory alloys. SMAs own a unique ability to return to a predefined shape after being deformed or heated. Super-elasticity allows them to recover from large strains, enabling adaptive structures and smart systems. Applications range from aerospace to biomedicine, with ongoing research focusing on perfecting their performance. This study analyses their historical background, their chemical composition, a comparison with conventional materials and some applications in aeronautics and aerospace such as actuators, vortex generators, variable geometry chevrons, morphing wings and superelastic tires for Martian and Lunar Rover vehicles.
