oedometern.

Brit.

/iːˈdɒmᵻtə/, U.S.

/ɛˈdɑmədər/,

/iˈdɑmədər/

Forms: 1900s ödometer (rare), 1900s– oedometer.

Origin: A borrowing from Greek, combined with an English element; modelled on a German lexical item. Etymons: Greek οἴδημα , οἰδεῖν , -ometer comb. form.

Etymology: < οἴδ- (in ancient Greek οἴδημα swelling, swollen condition or οἰδεῖν to swell: see oedema n.) + -ometer comb. form, after German Ödometer (Reinke, 1876).

A device for measuring the consolidation of a soil or other material when pressure is applied under controlled conditions.

1915 W. W. Taylor Chem. Colloids xi. 158 Reinke used the oedometer, by means of which he measured the pressure of imbibition, to determine the velocity of the process.

1926 C. Terzaghi in Colloid Symposium Monograph 4 73 My own tests performed with coarse grained sands, by using a method which in every respect corresponds to the Ödometer method for measuring the swelling pressure of gels.

1938 Nature 24 Sept. 584/2 From the results of tests made with the Terzaghi oedometer together with calculation of the distribution of pressure from the building, it is possible to estimate the amount of settlement to be expected.

1969 T. W. Lambe & R. V. Whitman Soil Mech. ix. 116 In the oedometer test, stress is applied to the soil specimen along the vertical axis, while strain in the horizontal directions is prevented.

1999 Nature 4 Mar. 32/3 We wetted a natural forest soil..to a water potential of −10 kPa, and compressed it at a pressure of 10³ kPa, measured using an oedometer.
