Based on the one-dimensional thermo-mechanical constitutive relation o
f a shape-memory alloy (SMA) in which the dependence of the elastic mo
dulus of SMA upon the martensite fraction is considered, a constitutiv
e relation for the bending of a composite beam with eccentrically embe
dded SMA wires has been developed. The deflection-temperature relation
upon heating and cooling has been analysed for the SMA-reinforced com
posite beam.
