Question

Difference between pseudo elasticity and super elasticity

Answer 1

PSEUDOELASTICITY
The shape memory effect is a very close to superelasticity phenomena (named also "pseudoelasticity").  Really, superelasticity assume as an reversible response to stress, caused by a phase transformation in some materials, so-called SMA materials.  The difference of these definitions is interpreted in the following way: superelasticity show us the type of deformational behaviour, traditionally relating to elastic one. On another hand, shape memory denote the possibility of body made of SMA materials, return to the old configuration. And, unlike SMA, superelastic materials may realize the reverse deformations without temperature application, only due to instability of their structure.  In this sense, SMA materials are controlled  superelastic materials.
