dc.description.abstractThe stressing at the inboard side of the oblique pressure vessel noizle is complex, and the design procedures in such cases are still in need of investigation. However, to JIlt the best of the author's knowledge, no complete analytical solution exists for predicting the effects on stress concentration a the inboard side of the oblique pressure vessel nozzle. Both ASME and BS codes only provide information for radial pressure vessel nozzles. Therefo~e, this research intends to provide information for oblique pressure vessel nozzle by investigating the 'effect of changing the skew angle, Alpha= 10°, 20°, 30°, and the dimensionless parameters such as Dff (Dff= 10,20), dID (dID= 0.20, 0.35, 0.50), and tff (tff=dlD or tff:;t:dID) ratios on the peak stress at the inboard side of the juncture of the cyUndrical pressure vessel nozzles. . " Ideas Master Series 1.20 is used to carry out the Finite Element Stress Analysis on the various pressure vessel models. The simulated results from the Ideas Master Series FEA package are compared to the benchmark data from the literature ~Moffit et aI., 1989). The simulated results are in good agreement to the experimental data . . By reducing the Effective Stress Factor (ESF), the fatigue life of the oblique pressure vessel nozzles can be enhc.llced. Thus, the future design of the oblique pressure vessel nozzle can be improved by 1< nowing what will be the consequences of ESF when the dimensions are being modified .en_US
