Hello,

I have a question about adhesion in composite. I would like enter in ABAQUS the level of adhesion (a value in N/m for the units) and I only find the maximal stress.

Anybody knows how enter the level of adhesive or a link between the maximal stress and the level of adhesion (the division by the lenght of the composite give bad results, very distant of the reality) ??

Thanks for your help.

Perhaps the strength values that you have found are related to the inherent strength of the base material, which is not the same as the interface strength between two materials (which can also be called the adhesive strength).

Yes, in fact the necessary value was the break stress and the simulation is good.

Thanks Jorgen:p
