Fig. 7. Percentage error of force-displacement curve evaluated by means of CBJE FE model.

The force-displacement curve of CBJE FE model demonstrates a highly relevant degree of matching with the one of the 3D FE Model, both before the static friction force F pre is reached and also after the external tensile force
