Abstract
The industrial development of shape memory alloys needs an accurate prediction of their behavior for using it in C.A.D. programs. The carrying out of such programs needs the definition of reliable thermomechanical constitutive laws. These laws are three-dimensional and therefore it is necessary, in order to perform an accurate identification, to do more than only tensile tests. In that way, this study presents some experimental results on the behavior of Cu-Zn-Al alloys under two different types of solicitations : uniaxial tension and simple shear. A first comparison between these two tests, in terms of stress equivalent, is also presented. The identification of the shear test results is performed using an elastohysteresis model.
