Orthogonal cutting damage layer definition.
2015-03-28 00:44:52 GMT
I am presently working on the modelling of orthogonal cutting process using ABAQUS. I was successfully able to validate the results using the ALE approach but I observed that there is a small hump like structure created at the start of the machining process, which looks a bit unrealistic.This paper may help you understand what the problem is :- http://www.researchgate.net/profile/Jafar_Takabi/publication/255610812_Simulation_of_Orthogonal_Cutting_Process_Using_Arbitrary_Lagrangian-Eulerian_Approach/links/004635222278b5818a000000.pdf.
Is there anyway to avoid this problem?
Also, there are a few papers wherein they have introduced a damage zone (sacrificial layer) where the elements get deleted and the chip forms as the tool progresses along the workpiece. Has anyone in this group worked on this approach before.For example the following paper, has used the approach to get the results:-
Thanks for your help and time,
