Non linear material property not captured in ANSYS simulation

Hi,

I analyzed one component with non linear material properties (Al material). I am using a multilinear kinematic hardening material model for this simulation . The plastic strain - stress properties are given as input after the yield point (YST ~ 48ksi). At the end of analysis, stress value of ~55 ksi observed at certain location. But the plastic strain is zero. From the stress - plastic strain table that I have given as input I expect it to show about 0.01 plastic strain. But I didn't get that value.

If anybody have faced similar issues and solved it or have some idea about what the problem could be, please help me out...

Thanks in Advance for your valuable input!
