摘要

假定厚壁梁的降温曲线为某种指数函数，推导出其自约束应力的计算公式，通过工程实例进行验算，表明本文的假定也比较符合实际情况。

Abstract

In the analysis, it is assumed that the distribution of temperature in the thick beam is expressed by an exponential function. The expressions of constraint stress are obtained for practical engineering cases. It is shown that the results are reasonable.
