Thermal Expansion Formulas
Linear Expansion
ΔL = α × L₀ × ΔT
Where:
- • ΔL = change in length
- • α = linear expansion coefficient
- • L₀ = initial length
- • ΔT = temperature change
Volumetric Expansion
ΔV = β × V₀ × ΔT
Where β ≈ 3α for isotropic materials
Common Coefficients
- • Steel: 12×10⁻⁶ 1/K
- • Aluminum: 23×10⁻⁶ 1/K
- • Copper: 17×10⁻⁶ 1/K
- • Glass: 8.5×10⁻⁶ 1/K
