Hello,
I am trying to simulate a beam test (2D) according to EN14651 (according to the attached figure). In the middle of the beam, a 4mm downward displacement is applied in order to simulate the test with displacement control. However, I have errors when inserting the MC2010 tension constitutive model, where there is a rise to the peak of tension, and after that the softnening occurs. Other models, such as the EHE (also attached) work without problems. The size of the increment, maximums and minimums have already been left very small, and I've also tried it using the arc length method (Static Riks). The constitutive model only gives 4 points of tension and deformation, so thinking that it would solve the problem, I interpolated more points, and played 12 in total. Unsuccessful too. Nothing works and the error is always the same: it is not converging (see attached figures). Can someone help me? Please?
hi dear friend
you have got too many attempts error
there is two way for you to debug your project.
first go to step module and edit your step change the maximum number of increment into a large number i hope this works otherwise
you should change your step from static general into dynamic explicit and do a quasi static analysis
This type of error can be solved by:-
1. remodel your problem or recheck all properties, boundary conditions and mesh type.
2. Use finer mesh size.
However, as I can see from the attached figures, I suggest you, to use ALE method of meshing or mesh refinement method. Which can be found in Abaqus User Manual or example guide.
Best Regards.
Hello, nothing that has been suggested is working. The strange thing is that for other similar models (the EHE-08, in the attached figure) the problem works. The model gives good answers! The only problem is when I add the MC2010 model (also attached). Thus, I deduce that boundary conditions and other variables are ok, and the problem is precisely in the CDP model. Any other suggestions? the errors are the same "the plasticity/creep/conector..."
