Dear Abaqus user experts,

I have been trying to use a simple model (a cylinder) to check the superelastic behavior of the material in uniaxial loading. I plotted the stress-strain curve for one element and compared the results with the input data. They do not match. I also observe high degree of oscillation in the stress curve in A to M transformation and during plastic deformation.

The BC is a smooth displacement to 10% strain.

Results also show that the ALLPD starts from where A-M starts, while the PEEQ starts at the plastic deformation point.​​​​​​​

I appreciate your advice in advance.
