Thermal Expansion Calculator

Formula

ΔL = α × L₀ × ΔT, where α is the linear expansion coefficient, L₀ is original length, and ΔT is temperature change.

Compute linear thermal expansion using ΔL = αL₀ΔT. Covers common materials like steel, aluminum, copper, and concrete with their standard expansion coefficients.

Common use cases:

  • Bridge expansion joint sizing
  • Railroad track gap design
  • Pipeline engineering
