Dear All,



I
faced problem in modeling Reinforced Concrete Beam considering discrete
reinforcement. Its a 10'X12"X6" sized beam reinforced with 2-10mm long
bar. I first model the concrete volume, mesh it & then create link
elements individually. The model shows ultimate load, deflection, mid
span stress very much close to theoretical values. But the problem is:
it doesn't show any crack/crush in concrete. I tried to get it, but
failed.

Hi all

I am M.Sc. sutdent in Istanbul Technical University and my research subject is comparision of several ductile damage models both computationaly and experimentally.

I am trying to compare ductile damage models such as Freudenthal,Cockroft,Ayada ,Brozzo etc. computationally using ABAQUS and seeking a way to implement these damage models in ABAQUS.

To obtain each models damage result individually should damage model be implemented in ABAQUS or  can a regular tensile test results be used for calculation of damage values.

Could you please advise me for methodolgy to run a simulation to obtain ductile damage values accordng to models mentioned above.

Thanks in advance for your help.

Hello,

It is some time that I am struggling for making a physical interperation of the MAXSCRT in ABAQUS  and crack initiation.

When the MAXSCRT in ABAQUS in cohesive element is equal to 1, does it mean that the crack has been formed or just it means that irreversible deformation in the element has been formed?

Thank you,
