Stefan-Boltzmann Radiation Calculator

Calculate blackbody radiation: q = ε·σ·T⁴. Stefan-Boltzmann constant σ = 5.67×10⁻⁸ W/m²K⁴. Net radiation between surfaces: q = ε·σ·F₁₂·A₁·(T₁⁴ - T₂⁴). Radiation heat transfer linearization.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.
