摘要
从热弹性力学的基本微分方程出发,利用位移势函数及补充解,在满足应力边界条件及位移边界条件下,得出了弹性基础上混凝土浇筑块温度应力的解析表达式。应用所得解析式计算了文中的两个算例,并与有限元解作了比较,两者吻合情况良好。
Based on the differential equations in thermoelasticity, using displacement potential functions and additional solutions, this paper gives analytic solutions of thermalstresses in massive concrete block on elastic foundation satisfying stress boundary conditions and displacement boundary conditions. Two examples are calculated by using the analytical formulas, the results are closely identical with the finite element solutions.
