1885 O. Heaviside in Electrician 9 Oct. 408/2 (bb). If in the final state (b), we unite P to Q by a second dielectric wire also of infinite capacity, we make a closed dielectric circuit which has no elastance (or elastic resistance to displacement).

1890 W. P. Maycock Pract. Electr. Notes (ed. 2) 48 Elastance is the reciprocal (or reverse) of Permittance; the comparative elastance of a dielectric is called its elastivity. For instance, a dielectric of great permittance has little elastance and vice versâ.

1890 Electrician 14 Nov. 41 The use of the words decalescence, reluctancy, reluctivity, elastance, elastivity, permittivity, might be well deferred till they are more generally adopted.

1893 O. Heaviside Electromagn. Theory I. ii. §31. 29 The formal relation of reluctance to reluctivity with magnetic force and induction, is the same as that..of elastance to elastivity with electric force and displacement.

2. Mechanics. The restoring force developed per unit deformation of an elastic body, substance, or system; the reciprocal of compliance (compliance n. 8).

1939 Bayliss & Robertson in Q. Jrnl. Exper. Physiol. 29 28 Elastance and viscance are to be distinguished from elasticity and viscosity; the former are properties of a system, and involve its geometry; the latter are properties of a material, and are independent of the size or shape of the specimen examined.

1953 Jrnl. Appl. Physiol. 5 784 Elasticity-like properties are described in terms of volume change in liters per elasticity-like pressure difference change in centimeters of water. This ratio is the inverse of elastance, as defined by Bayliss and Robertson.

1971 Jrnl. Appl. Physiol. 30 438/2 The elasticity of the lungs is expressed either as a compliance, the ratio of lung volume to the corresponding transpulmonary pressure change, or as its reciprocal, pulmonary elastance.

1987 Amer. Jrnl. Physiol. 253 H 1381/1 Using 10 isolated blood-perfused canine hearts, we determined the end-systolic volume elastance of each of these three compartments.
