n The modulus of volume elasticity, i.e., the resistance of a solid or liquid to change in volume with change in pressure, at constant temperature. The thermodynamic definition is:
in which v = specific volume, P = pressure, and T = the specific temperature. This may be approximated over an interval of pressure as 0.5·(ν2 + ν1)·(P 2 − P 1)/(ν1 − ν2). With plastics, B gradually diminishes as temperature rises and increase with rising pressure. (Mark JE (ed) (1996) Physical properties of polymers handbook. Springer, New York)
