摘要
采用基于突然损伤模型的有限元分析，研究了体积型缺陷的工程评定方法，提出将体积型缺陷简化为平面缺陷，并采用常用规范对简化后的平面缺陷进行工程评定的方法，还研究了共面平面缺陷的复合及自由表面对缺陷的影响，计算结果表明，该方法是安全的。
In this paper,an engineering assessment approach to volumetric defects has been studied using sudden damage model by 3D finite-element-method.The way which volumetric defect can be simplified as planar defects and which can be assessed by ordinary rule is presented.The interaction effects have been considered when there is more than one defect or a defect close to free surface.The numerical results indicate that the method is safe to be used in engineering.
