Abstract

This study concerns the pseudoelasticity of Shape Memory Alloys (SMA). A series of tests under tension-compression-torsion multiaxial loadings is used to show the validity of a conjecture concerning the relation between the volume fraction of martensite and the equivalent transformation strain. It is shown that the proportionality between an ad doc equivalent transformation strain and the volume fraction of martensite is confirmed under multiaxial proportional and nonproportional loadings.
