elastohydrodynamic1951
1951 De Ingenieur 21 Sept. O. 59/1 The above models lead us to an approximate elasto-hydrodynamic theory.
1969 Sci. Jrnl. Feb. 74/1 Sometimes the film of lubricant is so thin, and the fluid pressures acting on the bearing surfaces are so high, that the elastic deformation of these surfaces cannot be ignored; the regime is then called elastohydrodynamic.
1974 Nature 15 Mar. 219/1 Such viscometers always require a long period of time to build up the pressure on the fluid, typically an hour or more to reach pressures common in elastohydrodynamic contacts.
1979 Network (Melbourne) May 23/1 (advt.) The low torque seals..have bi-rotational elastohydrodynamic (EHD) mechanisms.
