This paper concerns the numerical developments of a probabilistic modeling of structural fuzzy in complex mechanical systems, the theoretical foundations of which laid down in the first part of the paper. We present further numerical analysis needed to implant the method in a finite element solver, along with certain elements identifying the behavior law of structural fuzzy we have built. We present a numerical simulation of the method on standard structures (beam-plate-shell).
