Metals and Alloys - Bulk Modulus Elasticity
The Bulk Modulus - resistance to uniform compression - for common metals and alloys. This tool provides reference values and allows calculation of bulk modulus using the relationship with modulus of elasticity and Poisson's ratio.
Bulk Modulus Elasticity
The Bulk Modulus Elasticity - or Volume Modulus - is a measure of the substance's resistance to uniform compression. It is the ratio of stress to the change in volume in a material subjected to axial loading.
Relationship Formula
Bulk Modulus is related to Modulus of Elasticity and Poisson's Ratio as:
K = E / 3 (1 - 2r)
Where:
- K = Bulk Modulus (Pa or psi)
- E = Modulus of Elasticity (Pa or psi)
- r = Poisson's Ratio
