Shape memory alloy wires can increase the critical temperature of the beam, and also can restrain thermal buckling occurring or make the post-buckled beam back to initial equilibrium states.
The objective of this article is mostly using characteristic of Shape Memory Alloy (SMA) to control the thermal deformation of antenna at orbit, ensuring the precision of antenna in a certain range.
