Hi, dear all,(adsbygoogle = window.adsbygoogle || []).push({});

Recently face some controversial issue with my supervisor and i cannot convince my self too.

is it time varying elastance equal to time varying young modulus?

Young modulus unit is Pa, however, elastance value is mmHg/ml, is both of them are equal?

Young's modulus, also known as the tensile modulus, is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. It is defined as the ratio of the uniaxial stress over the uniaxial strain in the range of stress in which Hooke's Law holds.

Compliance is calculated using the following equation, where ΔV is the change in volume, and ΔP is the change in pressure:[3]

as in the engineering software like ansys, comsol, adina, we only can set young modulus, so i wondering whether they are the same?
