Class 11 Physics simulations · Mechanical Properties of Solids

Compression and bulk modulus

Apply uniform pressure and compare a material’s change in volume.

Open the simulation

What to notice

A larger bulk modulus means a smaller fractional volume change under the same pressure.

Key relation

ΔV/V₀ = −ΔP/B

Try this

Compare a soft material with a stiff material.

What you can change

• Pressure increase: 0 to 400 MPa
• Bulk modulus: 5 to 100 GPa
