I am trying to simulate adhesion of metal sheet articles to forming dyes during SMF. It is called galling. I have a problem defining the required parameters to feed into ABAQUS, i.e Knn, Kss, Ktt. Do you have any idea?
in contacts of abaqus model under interaction modulus, it has many ways to define it, i recommend u to search contacts in abaqus, and there is so many tutorial for it, wish u best :)
You can try default enforcement method which is provided by abaqus
you can get some idea from it
You can find some useful instructions in the following paper: Selecting material parameters in abaqus for cohesive elements defined in terms of traction-separation. You can search and download from Google. Different methods are used depends on whether you have the experimental data of interface strength.
