摘要
开发了反应堆结构材料常规疲劳数据库管理系统。库中包含了常规疲劳设计分析曲线参量,即应力-寿命、概率-应力-寿命、应变-寿命、概率-应变-寿命、循环应力-应变及概率-循环应力-应变曲线参量,以及相关材料和试验条件信息。可通过材料名称或机械性能区间指标查询。根据查询结果,可进行常规疲劳设计分析与评价或常规疲劳可靠性设计分析与评价。
Management system of the conventional fatigue database for structure materials of nuclear power plant (NPP) is developed. In the database it is included the parameters of design curves, i.e., the stress-life, survival probability-stress-life, strain-life, survival probability-strain-life, stress-strain and survival probability-stress-strain curves, and corresponding information of materials and testing conditions. Two ways, by materials name or by the inter-bounds of material mechanical properties, are constructed to search the database. From the searched information it can be conveniently performed of the conventional fatigue design analysis and reliability assessment of structures.
