Bulk Modulus

Introduction to Bulk Modulus Calculator

The bulk modulus (K) is a measure of a material's resistance to uniform compression. It is defined as the ratio of volumetric stress (pressure increase) to the corresponding volumetric strain (relative decrease in volume). Mathematically, it is given by K = volumeStress / volumeStrain where volumeStress is the change in pressure and volumeStrain is the change in volume divided by original volume.

Parameter usage:

• volumeStress = pressure applied to the material
• volumeStrain = proportional change in volume (ΔV/V)

Output:

• bulk modulus = a measure of materials' resistibility to compression

Data validation

Both parameters must be positive numbers, representing physical reality.

Practical applications

The bulk modulus is commonly used in the fields of engineering and geology to describe the elasticity of a material when it is under pressure on all sides. It is also used in the oil and gas industry for reservoir simulations.
