Re: Example of concrete beam using beton Double DP

Can you share your experience using beton double dp for non-linear analysis? Does it converge well?

Re: Example of concrete beam using beton Double DP

I used BETON_DOUBLE_DP for 3d reinforced concrete beam and it converge almost very well. It is well defined plasticity criterion, so quite good numerical stability. It quite well fit the experimental data obtained on the laboratory measured beam.

Thanks for the encouragement. If possible, can you share some of your files so as not to reinvent the wheel.

Re: Example of concrete beam using beton Double DP

Hi,
Is there limitation on the size of element while using beton double dp? I got  error listed below while applying for RC beam which contains mesh for steel and concrete- resulting in small mesh near the steel-concrete interface.

Re: Example of concrete beam using beton Double DP

Hello,

yes the the model depends on size of finite element. It is necessary to use small 'enough' elements. You have to test the optimal size for your model.
