Materials Science Formulas
Materials science formulas for stress, strain, Young's modulus, hardness, thermal conductivity, fracture toughness, and fatigue life.
Coefficient of Thermal Expansion
Reference for linear thermal expansion ΔL = α × L₀ × ΔT. How solids grow or shrink with temperature — critical for engineering joints and tolerances.
Young's Modulus (Elastic Modulus)
Reference for Young's Modulus E = stress / strain. The fundamental material property describing how much a solid stretches under tension or compression.
Stress-Strain Formula
Calculate stress, strain, and Young's modulus for materials under load. Essential for structural analysis and material selection.
