Abstract : An elongated rod made of a shape memory alloy composition having selected pseudoelastic properties, is deformed into a dimensionally compact coil for packaged storage under stress maintained by physical constraint. Upon selective removal of the constraint allowing shape recovery, a substantial increase in axial length of the rod occurs in order to improve its performance in various installations, including long rod penetrating projectiles.
