Theoretical Research of Rapid Heating Semi-Infinite Object with Impacting Heat Flux

基于热量传播速度为有限值的双曲线型导热微分方程式,对实际中常见的冲击热流快速加热半无限体所产生的动态热应力问题进行了理论研究,分析了动态温度效应和热;中击期间动态热应力的变化规律。所得结果对完善发展热冲击理论及分析其机理都具有重要的意义。

This paper have made the theoretical research into the dynamic thermal stress problem of rapid heating semi-infinite object with impacting heat flux constantly seen in practice based on the hyperbolical conduction differential equation which thermal propagation velocity is finite value, and have analyzed the dynamic temperature effection and changing law of dynamic thermal stress during the thermal shock. The results are of great significance for developing the thermal shock theoretical and analyzing the thermal shock principle.
