Overestimated peak strength for cube compression. Abaqus/Explicit

Submitted by MrsTgr on Sat, 01/17/2015 - 10:47

Hi,

I have done compression test for concrete cube using Concrete damaged plasticity model. I assigned BC in Reference point which I coupled with a surf of the cube.

I have got stress-strain curve that looks nice, but Peak strength is 2-3 times higher than it should be.

Ia have uploaded pic of force-displacement.

Can anybody help me?

Thanks

I have requested for RF2

I have requested for RF2 reacion/force in Set1 for which I have assigned Reference point.

Thanks for interesting!

I am trying to do something

I am trying to do something similar but I am unable to make the the constraints works. Could you please upload your CAE file, that would be great and very helpful for me. Thanks a lot.
