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 takes place. A bi-linear and isotropic hardening elasto-plastic model has been employed to describe the stress-strain relation of the aluminum matrix. With the consideration of the fabrication procedure, the stress-strain behavior of the composite has been computed.
