Thanks, Bruno, I think I did not describe the question clearly. my question is how to get the force from the force boundary. for example, we use a rock sample to do the compress test. so we have to force boundary from the upper face and the the lower face. then how to get the foce on each grain from the boundary? we will say the force applied on the surface is 1000N, and the area is around 5 square cm, then how to convert the 1000N to the particle which contacting with the boundary (like a steel surface)?

There is no conversion from stresses to forces, the conversion goes from forces to stress. If you find a way to explicitely convert stresses into forces in a sphere packing with friction, well... you should apply for the Nobel Prize ;-).
