conventional hull
1.Conventional rice variety Teqing was employed for studying the physiological changes and the hull role to grain-filling at grain formation stage.
2.Because increasingly conventional fixed value method can’t adapt to evaluation demands of engineering construction which expect structure safety index to be much more exact, it is very important to carry through reliability research on overall longitudinal strength of hull and evaluate change of hull structure reliability during enlistment, which help to set up corresponding scheme to ensure safety of hull structure and settle theoretical foundation only to establish reliability analysis specifications of overall longitudinal strength of hull.
3.Abstract: 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.
