FEMFAT焊缝建模指导方针_BS7608英国标准

3月前浏览204

摘要:

本文为 FEMFAT 5.0 基于 BS 7608 标准的焊缝疲劳建模指导文件,系统给出各类焊接接头的有限元建模规范与材料编号映射。文档覆盖对接焊、T 型焊、十字焊、角焊、搭接焊及空心型材对接焊,区分全熔透与非全熔透、单面 / 双面、有无焊缝端部、打磨 / 未打磨等工况,明确对应 FAT 等级(C‑G、F2 等)与 MAT 材料编号。采用薄壳单元建模,规定焊缝节点标记规则、等效材料号对应关系、焊趾与焊根疲劳细节分类。直接对接英国 BS 7608 焊缝疲劳评定体系,为焊接结构疲劳仿真提供标准化建模与参数选取依据。
