Prior continuum models of van der Waals force between carbon nanotube walls assume that the pressures be either the same on the walls or inversely proportional to wall radius. A new continuum model is obtained analytically from the Lennard-Jones potential for van der Waals force, without the above assumptions. Buckling of a double-wall carbon nanotube under external pressure is studied, and the critical buckling pressure is much smaller than those models involving the above assumptions.
