Contact definition : Node or Surface???
Contact definition : Node or Surface???
(OP)
Hi,
I'm using ABAQUS/Explicit and i'd like to modelize contact between a tool and a sheet. I use a master/slave contact algorithm with penalty methods. To define the slave surface i can choose Node or Surface. I get results which are very differents from one to the others. What should I choose? Where did the difference come from? I think from interpolation...
Regards

RE: Contact definition : Node or Surface???
What does the documentation say about the underlying formulation used when choosing Node vs Surface ?

I've looked for explanation in the manual and I've found it yet.

ABAQUS Analysis User's Manual
-> 2.3.3 Defining node-based surfaces ??
"A node-based “surface”:
should be used with caution or not at all if accurate contact stresses are needed or if heat will be exchanged between the two surfaces;"
