How to assign materials property to cohesive element?

How to assign materials property to cohesive element?

How to assign materials property to cohesive element?

(OP)
Hi,in 3-D model of ABAQUS/CAE, we need to use keyword editor in order to assign materials property to the cohesive element? Who knows how to edit the keyword in Model->Keyword editors->Model_name?    

RE: How to assign materials property to cohesive element?

1. Create a material with name cohesive-mat. Supply just the density definition
2. Start the keywords editor (in the menu you mentioned)
3. Find the *MATERIAL keyword for the material named "cohesive-mat"
4. Paste the following lines after the *Density defintion:

*ELASTIC,type=traction
**<Emod>,<Emod>,<Emod>
1.0E6,1.0E6,1.0E6
*DAMAGE INITIATION,CRITERION=QUADS
**<ultI>, <ultII>,<ultII>
61.0,68.0,68.0
*DAMAGE EVOLUTION,TYPE=ENERGY,MIXED MODE BEHAVIOR=BK,POWER=1.45
**<GIc>,<GIIc>,<GIIc>
0.075,  0.547,0.547
**0.075,  0.60,0.60

5. Edit the coefficients to your own taste!
6. Create a cohesive section that refers to this material.
7. Assign the section to the specific region of the model
8. Make sure you have Cohesive element type assigned to that region (Mesh module)
9. Mesh the model and CHECK the stack direction (Tools-Query)

Hi, how to create a cohesive section that refers to the materials defined in the Key Word Editor?
I got stuck at step 6.

Hi, this is the eror messages.
*Conflicts, User edited keywords

I am using ABAQUS/CAE. For cohesive element, it is needed to convert SOLID part into SHELL part. Is it right?
