摘要
疲劳裂纹往往发生在船舶结构的局部高应力区 ,而疲劳分析结果通常取决于任何准确确定结构的应力集中系数。本文研究为铺设纵骨而在舱壁板上开孔的应力集中 ,采用有限元方法对预先给定的结构进行应力分析 ,基于有限元计算结果给出了舱壁板典型开孔(参见ABS油船规范)
Fatigue cracks in ship hull structures are most likely to occur in the highly stressed structural details.The conventional fatigue analysis is largely dependent on the determination of stress concentration factors (SCFs) at the locations considered.This paper is concerned with the stress concentration of cutout in transverse web for longitudinal stiffener.A series of finite element models is carried out for the stress analysis of predefined structural details.The tabulated SCFs of typical cutouts (ABS Tanker Rules) in transverse web for longitudinal stiffeners are presented based on the finite element analysis (FEA) results.
