i modeled a simple 15cm*15cm concrete block to check the behavior. and applied a compressive load.
problem is input stress-strain is not matching with output stress(S22) - strain(LE22) as in figure.
my doubt is S22, LE22 are correct components to represent or something else is there
I am pretty sure your input curve comes from the tensile test (since it shows brittle behavior), while your output is a compression case.
it will show different behavior since the concrete damage plasticity model is a pressure-dependent plasticity model. so depending on how you load, either tension or compression.. the yield strength changes

Dear Srikanth Kallam In addition to what Ditho Ardiansyah Pulungan underlined, I would like to recommend that you not only check the consistency of the units, but also make sure that the modeling is as realistic as the experiment leads to obtain the stress and strain.
Good luck !!!
