摘要
Abstract
Laws of distribution of the temperature changes are analyzed.The defect of Hills formula is pointed and the modified formula is proposed by mechanical analysis.Calculation indicates that the curling stress caused by uneven temperature distribution can not be neglected;the result of temperature stress calculated by Hills formula is smaller than that of modified formula;and the fracture temperature predicted by it is lower than that of modified formula.关键词
