The original formulation of the MRS-Lade model, with non-associated flow rule
on the meridian plane in the cone region, has a corner. In order to reduce the
computational effort of corner solution algorithms, a modified plastic flow potential
for the cone part is found in the literature. This modification may have a non-admissible
flip over of the flow vector in the cone-cap intersection if the plastic flow
potential is not correctly defined. Here a corrected plastic flow potential for
the cone region is defined to obtain a continuous transition of the flow vector.
