dear younes :
thank a lot for answer , this procedure catch the first cracks only ,
i mean the crack developments with change the concrete volume changes ,
i simulate that crack developments in ANSYS , but now i want to doing the same using Abacus software.
Some years ago, a collegue of mine did this.
I think you can contct him.
His name is Giampaolo Menichino.
If you don't him on research gate, look for him on linkedin
i tried to find his email but i cant fond any think in the LinkedIn also
[email protected] and [email protected].
Write him by saying I said You abuot our work on concrete cracking by ABAQUS simulator
I recommend you to contact either Dr. Ehsan Haghighat or Dr. Sina Moallemi at McMaster University. They are computational mechanics experts and currently developing new codes for such problems in ABAQUS.
Hallo Mr.Majid Ali,
Could you tell me the procedure for concrete crack development in ANSYS WORKBENCH....
the development of cracks in ansys is al ready did
only need to distributed the load to increments and connect this increments with time.
when display the time or increment it clear display the crack development when and where
The computer program ABAQUS/6.12, which is an FE based program, is used . This software offers an option to model concrete called “Cracking Model for Concrete” (CMC), which is only available in ABAQUS/Explicit. This is a special purpose analysis technique that uses an explicit dynamic FE formulation. Although developed for dynamic problems, the explicit version is very effective in highly non-linear problems under static loading /Kianousha et al. 2008/. In this study, CMC is used to simulate the non-linear behaviour of concrete under and after cracking. The model assumes that the primary forces in the structure are tensile and that the compressive forces are relatively small. For this reason, the non-linearity of concrete in compression is ignored. Since volumetric induced strains in concrete are mostly tensile and the tensile strength is low, it is very likely that cracking occurs in the concrete. The model includes the temperature variations, tension stiffening and shear retention in the concrete. The weak point in this model is that it assumes that the cracks start when the principle stress reaches the tensile capacity.
Hai friends,
Am doing a project on simulation of crack growth propagation in shell elements using ansys. I have designed the model and determined the stress intensity factor k1 using APDL codes.
It would be a great help if someone could help me in crack growth simulation
thank you.
