摘要：

The pressure tensor in the wedge-shaped cavity between solids with dispersion forces is calculated. All four (three diagonal and one off-diagonal) pressure tensor are calculated as functions of the position inside the cavity. It is checked that, if the cavity walls belong to different solids, pressure tensor depends, not only on the opening angle of wedge-shaped cavity, but also on the position of interface between contacting solids. In this case, the absence of cavity symmetry leads to different values of normal pressure on opposite walls, thus complicating the determination of disjoining pressure. The region of configurations of bodies in which this determination can be made is found.
