Thermoelastic structural failure maps in the D - L design space at (a) ΔT<sub>rod</sub> = 50 K, (b) ΔT<sub>rod</sub> = 120 K, (c) ΔT<sub>rod</sub> = 300 K, and (d) ΔT<sub>rod</sub> = 500 K. Each map identifies safe, buckling-controlled, yield-controlled, and combined-failure regions under the same structural assumptions and safety factors.
