摘要
研究了低功率密度激光辐照结构的热动力失效。考虑材料的高温软化特性，研讨了温升速率对材料和结构的影响、结构热软化后的宏观受力和变形的重新分布以及可能的热运动。给出了几种热动力失效的结构破坏实验结果。
The thermodynamic failure of the structures irradiated by laser beam with low power density are studied in this paper. Considering the effect of heating rate and thermo-softening of material, the redistribution of macro-stress and deformation in structures and the possible heat inducing motion are discussed. Some experimental results of destructive tests of structures are presented.
