ABSTRACT:
A noticeable two-way effect can be induced in a component consisting of a shape memory alloy exhibiting only a one-way effect by inhomogeneous deformation of the cross-section so that one part of the component cross-section is deformed sufficiently to hinder the free movement of the one-way effect in the lesser deformed part. Component in the form of a tension/compression (6/8), bending (3), or torsion rod.
