Relation Between Young's Modulus and Bulk Modulus

Relation Between Young's Modulus and Bulk Modulus

### Formula

$$Y=3K(1-2\sigma)$$

### Terminologies

- K → Bulk modulus.

- Y → Young's modulus.

### Conditions / Special Cases

For incompressible material:

$$\sigma=\frac{1}{2}$$

Therefore:

$$K\rightarrow\infty$$

### Usage

- Used in elasticity calculations.
