you can model the unit lattice using the Material designer included in ANSYS WB and set the repeat count to desired value.
then you can proceed to save the geometry as .scdoc file from material designer and you can import the saved CAD into workbench as follows
based on the your definition of having those D1,D2,D3,D4 and D5 are called as JC-Damage constants these are used for predicting the erosion on ground terms "Breakage". Well you also need to have elastic and JC-plasticity parameter as follows
you can do QUSI STATIC by changing the type in Analysis settings as follows. Moreover, you need to know the minimum CFL time to proceed further.

to make sure your structure follows the material failure law make sure you enable the following option.
you can use the RAM HEAD like geometry and apply a displacement vs time cure to apply the compression load at given strain rate.
Comment down your results for further help.
