For memory effect in drying pastes, reported by Nakahara and Matsuo and referred to as Nakahara effect, a possible clarification is given in terms of a macroscopic theory that predicts creation and retainment of tension in the direction of the external forcing. While the previous version of this theory was restricted to the two-dimensional stress field, now the theory is extended to the three-dimensional cases, which predicts not only residual tension in the direction of external forcing but also residual pressure in the perpendicular direction, thus confirming the presence of anisotropy in the horizontal plane.
