How to set up the boundary condition for the following problem in Abaqus (Image is attached).
The feedstock will corotate with the hollow rotating tool and one pusher will push the feedstock through the tool over the substrate.
Kindly help me to set up the model. I am little bit confused with boundary conditions.
Hi Debanjan Maity,
The boundary conditions will be similar to the friction stir welding process:
- Thermal boundary condition:
- Mechanical boundary condition:
To model the deposition of material on to the substrate, delete the elements and activate them sequentially.
Hello Kumar Ujjwal,
If you see the process its different from FSW. In FSW the tool pin penetrates into the workpiece. Here the rigid tool does not have any pin, rather hollow in nature. A feedrod is feed through the hollow tool.
The hollow tool is having only rotation constraining all other DOFs. But the feedrod will initially corotate along with hollow tool at same RPM and will have a downfeed by some actuator to cause both compression and shear at the contact interface of feedrod and substrate.
The hollow tool only restrict the vertical motion of the material flow of the deformed feedrod.
So here I think the BC is little bit tricky.
