In the charts of Fig. 11, can be seen the FEA strain vs the Maximum Theoretical Strain (MTS) for the 0.58mm diameter wire and the 0.25mm diameter wire, for both tension and compression, as the strain slightly differ.

FEA Results - Stress in the cross section of the Specimen The stress along the cross section of the specimen shows the amount of material which is in the austenitic phase or already in the Austenite to Martensite transformation phase.
