I am trying to input the material data in ansys mechanical with the help of command i have.This experimental data only consists of stress strain value of concrete cubes.I dont know where this code is wrong can anyone help me out?

Hi,
it seems that in this code there is nothing wrong. Why do you think that there is something wrong?
Thanks for your response Marco Gaetani d'Aragona .When i am running the file there is an error .I am attaching the image of error kindly go through it
The first error is quite simple to solve: the elastic modulus given with code line "MP, EX, MATID, 24494.89743" is not coherent with points defining the backbone for concrete material: " TBPT,, 0.0000743587466901018, 12.8755285836629 ...and so on ". To solve this error you should adopt Ex equal to 173154.1904 or to change the first point of the backbone. The second error is similar, while the third is due to an error in step definition. I suggest to check the file indicated as file0.err.
I am attaching the file0.err and my code file. Also i am not that good with coding i am trying to learn it but there aren't any suitable resources available.And i need the Ex value to be 24494.89743 along with the values of my graph to be same i can't change it as they are experimental results.Could you suggest what to do ? Marco Gaetani d'Aragona
i think that the backbone has some problems since a concrete modulus Ex=173154 is not realistic, However, in order to try if the model works I suggest to firstly set E= 173154.1904 and see if the model runs correctly, then it is possible to act on the incompatibility between the backbone and the elastic modulus. For what concerns file0.err, you should search in the path "C:\Users\Aakash
Shukla\ansys2020r1\_ProjectScratch\ScrFB5E\file0.err" since the file0.err attached at your previous response only contains this text:

"
Further, I think you defined material 9996 also elsewhere since there are two errors that appear:
1) the initial slope of the stress-strain curve based on the TB,MELAS table ( 173154.19 ) is greater than EX (24494.8974).
2) has a tangent slope of its stress-strain curve ( 40953.8255 ) greater than EX ( 24494.8974 ).
