Bulk Strain


Quick
Bulk Strain may also be known as volume strain.


Equations
(Eq1)    
Bulk (volume) strain =
ΔV
V0
Bulk strain


Nomenclature
ΔV--
V0--


Details

Pressure plays the role of stress in a volume deformation. The corresponding strain is the fractional change in volume V0:

(Eq1)    
Bulk (volume) strain =
ΔV
V0

Volume strain is the change in volume per unit volume. Like tensile or compressive strain, it is a pure number, without units.
