In Abaqus/CAE 2020, cohesive penalty stiffnesses CAE labels are
E/Enn, G1/Ess, G2/Ett,
and the values entered there show up in the Abaqus input file under *elastic,type=traction,
but in the documentation for Abaqus input file it says that in *elastic, type=traction, those numbers are
*ELASTIC, TYPE=TRACTION
Enn, Ess, Ett
So which one is true, in CAE, should I enter values of Enn, Ess, Ett or what?
I know from the documentation that the so-called penalty stiffnesses are Enn=E/To, Ess=G1/To, Ett=G2/To, where To is the thickness of the adhesive, E modulus of elasticity of adhesive, and G1=G2=G=E/2/(1+nu) for isotropic adhesive.
But my point is that the notation for those values in CAE is wrong. Is it?
*elastic, type=traction notation error in CAE
