核压力部件缺陷全息无损检测的有限元分析

针对核压力部件所含典型缺陷，建立简化缺陷的力学模型，采用有限元数值法计算和讨论了两种极端缺陷的大小与深度，材料性质及内压值之间的关系，为了考查计算的可靠性，文中对所建立的缺陷力学模型按Ｔｉｍｏｓｈｅｎｋｏ理论进行计算和在缺陷的钢容器上进行双爆光全息干涉实验，理论和实验结果表明，所做缺陷模型的有限元分析计算结果有足够的精度，且计算数据可为核压力部件全息无损检测研究提供参考。

The Finite Element Analysis of Holographic Nondestructive Testing for Pressure-Containing Member

To counter representative defects in a pressure-containing member,a simplified defect mechanical model is established and the relationships of the size and depth of two extreme defects, properties of material and internal pressure are calculated and discu
