enABAQUS (6.8, 6.9 EF) - Effect of the number of back stresses
https://imechanica.org/node/8115

Since ABAQUS 6.8, a new feature has been added to the combined hardening<br />
material input.
</p>
<p>
Let's assume a combined Kinematic and Isotropic hardening case, such as<br />
those happen in metals.
</p>
<p>
"Half cycle" uni-axial test results has been utilized to model the yield<br />
stress-plastic strain behavior as well as the Kinematic behavior of the<br />
metals.
</p>
<p>
In the same user interface, there is an option to choose the number of<br />
back stresses.
</p>
<p>
Is the number of 1 back stress is equivalen to the case of linear<br />
kinematic hardening (Ziegler's)?
</p>
<p>
Similarly, does it mean higher values for the number of back stresses<br />
trigger nonlinear kinematic hardening in the ABAQUS model? If so, does<br />
it mean using higher values for the "number of back stresses" option<br />
when half-cycle input data has been used, more closely predict the<br />
kinematic hardening behaviour of metals/models?

Thank you,
