Heat a material and it expands: ΔL = α·L·ΔT, where α is the coefficient of linear expansion. Area grows at twice that rate and volume at three times. It is why bridges have expansion joints, why rails buckle in heat, and why Invar — with almost zero expansion — is prized for precision instruments.

Length change11.5 mm

Area change0.230 m²

Volume change3.450 m³

Governing equation

Δ L = α L_{0} Δ T = (23 \times 1 0^{- 6}) (10) (50) = 11.5 mm

Reading this result: Heating 10 m of Aluminum by 50°C stretches it about 11.5 mm; area and volume grow 2× and 3× as fast.

Applied strain

Pull on a material and its stress-strain curve tells its story: a straight elastic region with slope equal to Young's modulus, a yield point where permanent deformation begins, a peak at the ultimate tensile strength, and finally fracture. Ductile metals stretch far; brittle ones like cast iron snap with almost no warning.

Governing equation

σ = E ε, E = 200 GPa, ε = 0.050, σ \approx 294 MPa

Reading this result: Past yield (250 MPa): Mild steel is deforming permanently and hardening toward its 400 MPa ultimate strength.

About this simulation

The full Weld Design tool models a solubility curve with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
