摘要
本文以快速瞬态导热微分方程式(双曲线型)为基础,对在自然状态下冲击加热半无限体产生的动态热应力问题进行了理论求解并对热冲击期间温度和应力的变化规律做了较深入的分析和讨论.所得结论对热冲击问题的理论研究及实际问题中热冲击损伤机理的研究都具有一定的价值.
In this paper, dynamic thermal stress problem of heating semi-infinite object with impact in steady state is solved based on the rapid transient conduction differential equation. And rate of temperature and stress during impact heating are analyzed and discussed. The results of the paper is valuable for theoretical research of impact heating and the reason of heating injury in practical problem.
