Hi,
I want to give half-cyclic curve properties of a material to get the plastic behavior of the component during cyclic loading.
I have the values of stresses and strains as shown below
0 0
25 0.010973478
50 0.022751482
75 0.036091362
100 0.051730571
125 0.070394475
150 0.092799677
175 0.119655902
200 0.151667218
225 0.189532897
250 0.233948042
275 0.285604082
300 0.345189153
325 0.413388419
350 0.490884324
375 0.57835682
400 0.676483548
425 0.785940002
450 0.907399671
475 1.041534159
500 1.189013297

I tried to input them in Property->Material->Mechanical->plasticity->Plastic

It asks for Yield stress and Plastic Strain in a table. I have entered the values (above). But it says that "Tabular data for at least one option or suboption has either blank or zero valued row(s). I then changed the first yield stress from 0 to 0.01 and submitted the job. Is this way correct?

Is there any other way to input the data for the half-cyclic curve?

Thanks in advance.

This standard plasticity definition requires non-zero yield stress and zero plastic strain as the first entry.

Check the documentation chapter Materials —> Inelastic Mechanical Properties —> Metal plasticity —> Models for metals subjected to cyclic loading". There you can also find information about cyclic hardening option.
