How much is the allowed maximum stress in contact for separation ?

Hi All
If you have to define a stress limit for a contact node, how much would be that stress , ( in an arbitrary condition ) is there a rule of thumb ?

RE: How much is the allowed maximum stress in contact for separation ?
In Abaqus I've never seen such an effect, beside when I've created it on purpose to simulate interface failure.
But in general: since it is a artificial and unreal effect, these stresses should be very small compared to the overall stresses in that region.
