Concrete branch ready for testing

[bernd]

Harry how about fy for the test cases?

[HarryvL]

What do you mean Bernd? Fy = yield strength? Context?

[bernd]

I am writing a unit test for your rho calculstion def. input and output will be three or four posts before this post. But I need a yield strength too.

[HarryvL]

How about the unit test Harry?
...
Are the values above the input and output values?

With this information a unit test is very easy do develop. I would go for this if you don't mind.

Sorry Bernd, I missed your question.

Sigma = sxx syy szz sxy sxz syz is input
Rho = rhox rhoy rhoz is output.

This can therefore only test the routine for calculating the reinforce ratio.

This assumes fy=500MPa and concrete tensile strength of 3MPa. I need to check how I accounted for the tensile strength in the verification code b

I am trying to do a few test cases but don’t know how to use the ReinforcedMaterial object. How do I link a steel and concrete object to this?

there you have a normal material object and nog a reinfoced material object.

I don't see if or how I accounted for tensile strength. Let me read the original article again, because I do reproduce the right output.

Ah I remember now. The reinforcement calculation ignores concrete tensile strength. Equilibrium at failure assumes the concrete is cracked and normal stress along the crack is taken by the steel in yield. The value of tensile strength in the article is only used in the crack width calculation. Something we may consider for future enhancement.

Yes, but I cannot do anything with that object. Do I still have to use Python to link material objects to the reinforced material object?
