1885O. Reynolds in Proc. Brit. Assoc. 896 (title) On the Dilatancy of Media composed of Rigid Particles in Contact. ― Ibid., A very fundamental property of granular masses. To this property he [O. Reynolds] gave the name of dilatancy. It is exhibited in any arrangement of particles where change of bulk is dependent upon change of shape. 1886Sat. Rev. 28 Aug. 295 Owens College had at that time only begun to display its ‘dilatancy’, if we may make bold to use a term recently applied by one of its professors to a force which he claims to have discovered in the physical world. |
