摘要

摘要: 建立了正交各向异性材料二维率相关的弹塑性本构模型，采用有限元方法编写程序，对X射线辐照各向异性材料碳酚醛平板时诱导的热击波进行了二维数值模拟，讨论了热击波的传播规律。结果表明，在软X射线和硬X射线的辐照下，材料中的X射线热击波表现出不同的形貌，材料中热击波形成的机理、热击波峰值、X射线穿透深度、汽化现象、拉伸强度等方面均存在很大差异。

Abstract: Using anisotropic elasto-plastic constitutive model, the 2-D thermal shock wave induced by X-ray in anisotropic material is simulated by finite element method, and the thermal shock wave propagation rules are discussed. The results show that the thermal shock wave exhibits different shapes under the radiation of soft and hard X-ray, and there are great differences in some other aspects, such as thermal shock wave forming mechanism, wave peak value, penetration depth of X-ray, gasification phenomenon, tensile intensity and so on.
