Abstract:
A special combined tension-torsion testing machine has been developed for the shape memory alloy microtube which is becoming more and more widely used. Shape memory alloy may be subjected to martensitic phase transition under stress. There is multi-scale effect in its mechanical behavior. Accordingly, the testing machine offers a series of combined tension-torsion loading paths with high-precision control, achieves normal and shear stress measurement by a single elastic component, achieves non-contact, direct, synchronized, and full-field normal and shear strain measurement based on digital image processing, and provides optimized lighting for photographing of the morphology evolution of specimen surface. By this machine, we first complete systematic quasistatic combined tension-torsion tests on shape memory alloy microtube and find some new phenomena of deformation instability. It is valuable for the research on the constitutive relation of this kind of material.
