help with 4 point bending test smilation

[Dassrf]

Hello guys im try doing a nonlinear simulation by using ansys workbench
i need to probe results shown by using digital image correlation technique applied to a 4 point bending test
the results that i need to probe are
displacement in z axis(is already done)
strain map in y axis (is here where i have my problem the DIC show the strain in Y axis is 4.25 and my result using ANSYS is .0045 that is quit far)

i dont know what to to
im using multilinear isotropic hardening table to introduce data

anyone can help me whit this problem


regards
