Thermal stresses set up in cellular wing structure when aircraft is subjected to change of speed or of altitude; for wings with little or no insulation maximum stress in wing is usually between 70 and 85% of value given by Young's modulus for webs X coefficient of expansion for skin X external temperature change; conclusion is that of metallic materials, combination of light alloy webs with steel skin is admirable for reducing thermal stresses.
