simulation in cutting

[benmohamedsalem]

I simulate the model of the oblique cutting, my problem is to have the separation of the chip when the tool advances, is what there is a criterion of separation if not how I want to do that
I used the critère Johnson Cook
(A = 612 MPa; B = 436 MPa; = 0:001 1/s ; n = 0:15; m = 0:008; m = 1:46; Tr = 296 K Tf = 1793 K ;
The other material parameters are given by : =7800 kg/m3 ; c = 500 J/kg K; k = 54 W/m K
The parameter of damage : (D1: 1.5; D2: 3.44; D3: 2.12; D4: 0.002; D5: 0.1)
I applied to the part an encastrement (U1=U2=U3=UR1=UR2=UR3=0) of bottom and in arriere and to the tool I applied a speed (V=5m/s) in the point of referance.

My guess is that you need to post your model to get much help or in detail explain all your settings. The first one is are your in Explicit or Standard....

I know that I have much difficulty in this model, but I answer each time at the request of detail, I use abaqus explicit in this model, I entered these data in this model, I had a contact between the tool and the part, I worked in 2d but I remove an element to have a separation of chip, but in 3d is not the same one, this is why I seek of assistance.

is what there is a criterion of separation which can help me louse separer the chip of the matter in the abaqus explicit.
