Hello Dmytro,

Can you post-process the history variables using LS-PrePost?

Did you set NSHV on *INTERFACE_SPRINGBACK_LSDYNA to a large value? Here is more information from the LS-DYNA User Manual Vol I:

NSHV Number of shell or solid history variables (beyond the six stresses
and effective plastic strain) to be initialized in the interface file. For
solids, LS-DYNA writes one additional state variable (initial volume).
If NSHV is nonzero, the element formulations, unit system,
and constitutive models should not change between runs. If NHSV
exceeds the number of integration point history variables required
by the constitutive model, LS-DYNA only writes the number required.
Thus, if in doubt, set NHSV to a large number, such as 100.

Which version of Ansys Workbench are you using?
