Control of Intrinsic Instability of Superelastic Deformation



Julia Slutsker, Alexander L. Roytburd


The superelastic deformation of shape memory alloys has intrinsic instability as a result of incompatibility between martensite and austenite phases at stress-induced transformation. The instability leads to the stress-strain hysteresis of the superelastic deformation. It has been shown that the combination of a shape memory active material with a non-transforming passive material allows one to decrease and control the stress-strain hysteresis. The stability analysis of superelastic deformation of a composite allows one to design an adaptive composite with controlled stress-strin hysteresis.
