Glass Thermal Stress Here

σ=E⋅α⋅ΔTsigma equals cap E center dot alpha center dot cap delta cap T

# 4. Check Safety is_safe = induced_stress < limit safety_ratio = induced_stress / limit glass thermal stress

return "delta_T": delta_T, "stress_MPa": induced_stress, "limit_MPa": limit, "is_safe": is_safe, "risk_level": "High" if safety_ratio > 0.9 else ("Medium" if safety_ratio > 0.6 else "Low") σ=E⋅α⋅ΔTsigma equals cap E center dot alpha center
