David Alber is still having a problem:
@Jerome Duriez: 
1)
Thanks for your answer. Having a closer look at the example of the workflow, provided the answers I needed. It seems that not only the body property 'onJoint' needs to be true, but also the joint normal vectors need to point in the right directions. If both conditions are fulfilled the stiffness kn is calculated from the jointNormalStiffness. 

@Luc Scholtes:
2)
>just define cohesion and/or tensile strength between particles without changing the contact plane orientation (without playing on the onJoint attribute)<
Indeed the aim is to 'glue' particles together with cohesive bonds and changing the contact plane orientation is not a necessity. 
What constitutive law would you recommend to achieve these cohesive bonds? 
Are you referring to the Law2_ScGeom6D_CohFrictPhys_CohesionMoment law with the corresponding CohFrictMat material class? 
As far as I understand, the parameter normalCohesion/ shearCohesion define a maximum tensile strength for the bond, which breaks if the force exceeds this value. Right?
