Iam modeling and analysing a simply supported RC Slab using ABAQUS 6.8.2 with static Riks Concrete Damaged Plasticity. My results show that the behaviour of the deformation seems to continue up to 1000mm. My query is that how to set ABAQUS so that the RC slab will fail in a realistic manner either in crushing (compression) or cracking (tensile failure) with reasonable maximum deflection value. Please let me know how to fix this problem. Thanks

Iam working on the analysis of simply supported RC Slab using ABAQUS with Concrete Damaged Plasticity. Anyone knows the ideal or best data or expressions or formulaes to relate the yield stress and strain (or displacement or GFI) for tension behavior in the tension stiffening profile.

Please let me knows. Thank you.

Dear Abaqus Users,

Dear Abaqus Users,

I have modelled and analysed a simply supported RC Slab strengthened with FRP using ABAQUS 6.8-2. Plastic analysis with Concrete Damaged Plasticity has been chosen to simulate the behavior of the RC Slab loaded at the centre. However, I have difficulties about the constraints between the surface of FRP and surface of the RC Slab. Abaqus did not recognise "tie" element for this interface between these materials. A good comparison between this simulation and the experimental test result is expected. However, tie constraints made the analysis to be terminated.
