How to Calculate Materials Science
What is Materials Science?
Materials science calculators compute fundamental mechanical properties — Young's modulus, shear modulus, Poisson's ratio, and stress-strain relationships — enabling engineers to select and analyse structural materials.
Step-by-Step Guide
- 1Young's modulus: E = stress / strain = (F/A) / (ΔL/L)
- 2Shear modulus: G = E / [2(1 + ν)]
- 3Poisson's ratio: ν = −lateral strain / axial strain
Worked Examples
Input
Steel rod: F = 50 kN · A = 500 mm² · ΔL = 0.2 mm · L = 1,000 mm
Result
E = (50,000/500) / (0.2/1000) = 200 GPa
Steel E ≈ 200 GPa; Aluminium ≈ 69 GPa; Concrete ≈ 30 GPa
