Abstract: | The purpose of this study is to provide a numerical method to model the constitutive behavior of aluminum matrix NiTi fiber-reinforced smart composite along the fiber direction; in the present approach, pseudo-elasticity, shape-memory, and strain-hardening effects have been taken into account. During phase transformation, the strain-temperature relation of NiTi fibers has been assumed to be linear. Hence, the incremental stress-strain relationship of the fibers has been derived for each temperature range where phase transformation lakes place. |
