摘要
工程中的构件和零部件如果存在裂纹和缺陷,会给该工程带来灾难性的后果。在工程设计和评定阶段,需要尽可能准确地评估构件中裂纹的应力强度因子,因为这一参数是预测含裂纹构件断裂的主要依据。以工程结构中常见的含孔平板为研究对象,利用ANSYS有限元分析软件计算孔边的裂纹尖端应力强度因子,分析得出对工程应用有重要参考价值的结论。
The project components and spare parts for cracks and defects if, the project would have disastrous consequences. In engineering design and assessment phase, members need to assess the crack stress intensity factor as accurately as possible, because this parameter is the main basis for predicting crack-containing component breakage. In engineering str^ctures common-well plate containing the research object, the use of crack-tip stress intensity factor ANSYS finite element analysis software to calculate the edge of the hole, the analysis results of the en^ineerin~ conclusions have important reference value.
