Mechanical properties and advanced subjects in shape memory alloys and polymers

Advanced subjects in mechanical properties of shape memory alloys and polymers are di-
scussed. In the subloop loading under a stress-controlled condition of the shape memory
alloy, the transformation-induced stress relaxation appears due to variation in temperature.
The enhancement of corrosion and corrosion fatigue life of the shape memory alloy is discus-
sed. The development of a functionally-graded shape memory alloy and polymer is expected
to obtain better performance. Three-way motion appears in the shape memory composite
with the shape memory alloy and polymer.
