There is the brefcom model (in extra) that is supposed to do just that (cohesion) and is formulated using continuum mechanics (strain/stress) rather than particles and there is code to make the transition from displacements/positions etc to normal strain, shear strain and back from stresses to forces. The material model itself cannot be disclosed, but you can easily add your own. It is pretty much work in progress now, however.
For cohesion, make sure you use enable distant contacts in PersistentSAPCollider and InteractingSphere2InteractingSphere4SpheresContactGeometry. The old approach would use persistentContacts, but there are (by general consensus) deprecated and will be removed.
