Concrete07 possible typo in the epsilon_c0?

[arbarbosa]

I think there is a typo in one of the expressions shown in the manual for the parameters used to define the Concrete07 uniaxial material model.

In the SI Metric units part, I think that the denominator of the \epsilon_{c0} should have a value of 1153 instead of 28.

I'll ask the material's author.

You 're right

there' s a typo, the nominator should be 1153, that is 4000/(145^0.25), instead of only 4000/145.
