摘要
Abstract
A 2-D harmonic axisymmetric element was used as a simple method in fatigue analysis of noz-zles,which was attached to pressure vessel with piping loads.Methods of simplified elastic-plastic analysis and poisson′s radio correction were applied in fatigue analysis,with a view to the poisson effect.Based on the contrastive analysis of the calculation results,it turned out that the poisson effect can greatly affect the fatigue strength of pressure vessel.Simplified elastic-plastic analysis was the most convenient and the over-conservative method.Poisson′s radio correction took second place.At the same time,plastic analysis was the most precise method but not recommended,due to the calculation and test cost at a price.关键词
