【Abstract】 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.更多还原
