Cyclic tests - tension compression torsion

Hi,

I have got experimental data for a steel material for a cyclic test perfoemd in the following scenario:

0-1% Torsion followed by
0-1% strain Tension followed by
1-2% Torsion followed by
1% to 0 % compression followed by
2 to 3% torsion followed by
0 to -1% compression followed by
3 to -1% torsion followed by
-1 to 0% tension followed by
-1 to 0% torsion

I'm attaching the figure- that is: the stress strain curve for the tension compression cycle i.e for the cycle corresponding to 0-1% strain- 1% to 0% compression - 0% to -1% compression and -1 to 0% tension.

I have indicated the branch corresponding to loading and unloading in the figure that I'm attaching.

I'm currenly not able to establish contact with the experimentologist- meanwhile could anyone please let me know what does the flat portion indicate? (I have marked the portion).

The fattached file is named flat_portion.jpg.

I shall be grateful if helped.

Vishal
