Hello everyone, I am doing a simulation of orthogonal metal cutting process using CEL method. To make sure the simulation is better, I found a very good SCI paper for reference, but unfortunately I didn't reproduce the perfect chip simulation in the author's paper, the picture below shows the...
FEA way, My dear friend. Thank you very much for your answer. I read a lot of literature that the ALE method doesn't need to specify the chip separation criteria, so I didn't set up the damage model and turned off the element deletion. I saw that there is a blogger on YouTube...
Hi everyone, I've recently been using Abaqus/Explicit to do a finite element simulation of 2D metal cutting using the ALE method, and I've seen a blogger on YouTube do a similar simulation(https://www.youtube.com/watch?v=6wVFSw94Rkk). Still, his results are much more normal than mine. Doesn't...
Hi, everyone. I want to ask a question about the JC damage model that has been bothering me for a while now, and I feel that it might turn my previous knowledge upside down. Is the strain value calculated by the Johnson-Cook damage model used in Abaqus software the fracture strain? Or is it the...
Hello, everyone. I carried out the finite element simulation of the metal cutting process in Abaqus/Explicit, but there was a serious error report in the mesh distortion, and the simulation was aborted. Later, I reduced the mesh size by half, and the failure displacement was also reduced, but...
Hi, FEA way, My operating system is win10, and I do the Abaqus/explicit simulation. I have searched the "newest hotfix for Abaqus2022" just now, but it seemed there was no suitable fix for Abaqus2022 yet[sad].
Hi all, My computer has 2 cores(4 logical processors), and I set the number of multiple processors in Abaqus is 4. I submitted the job in Abaqus2021, and it ran well, but it was aborted and prompted the errors as I submitted the job in Abaqus2022. The error was "The number of cups (4) exceeds...
Hi, FEA way and g.alshamsi, Thanks for your help. And I have run the cutting simulation under two situations; It seemed that contact type(Kinematic contact & Penalty contact) do not affect the result.
Hi all, I'm running a metal cutting simulation with Abaqus/explicit. Generally, I use the Kinematic contact between the tool surface and workpiece surface(node-set), but when I set the rigid tool to rotate, it suggests that I can't use kinematic contact anymore, I have to use penalty contact. I...
Dear FEA way, I appreciate your patient answer.
I have tried so many times, including the below parameters setting.
but the result shows that The layer of mesh where the workpiece constraint surface(coupled with RP) is located disappears, and the workpiece rotates only at a small angle. I...
Dear FEA way, Thank you so much.
The .inp file is too big to upload(over 20Mb), so I have to make it into a zip file.

Dear FEA way, the following picture shows ALLKE vs ALLIE, and I have restricted energy output to the workpiece, but it obviously doesn't meet the 5% requirement. The mass scaling factor is 100, and it takes me about 5 hours[sadeyes].
Hi FEA way, thanks for your answer, the boundary condition I set for my circular tube workpiece is the angular velocity, which is 628 radius/s(100 cycles/s), and the velocity of my tool is 200 mm/s. The step time is 0.02s; I feel the angular velocity in simulation isn't high-speed compared to...
