Problem in Eulerian Method in Cutting Process

Problem in Eulerian Method in Cutting Process

Problem in Eulerian Method in Cutting Process

(OP)
Hi All,
I am trying to simulate cutting process using combined Eul and Lag Methods. The workpiece is simulated as Eulerian domain and cutter is simulated as
Lag domain. The cutter and workpiece interaction is gereral contact. The problem I found is the materials in the element under the cutter all disappears (becomes void) as cutter cutters. However, only a very small portion of the element has been cut through by cutter which should not result in the whole void of the element. Could someone give me some idea on this? Thanks.


Best
Oliver
