| Abstract: | In this paper, a stress distribution analysis is made by means of finite element analysis for cylindrical vessels subject to internal pressure. The varying laws of the stress distribution are found out which is subject to opening ratio, space in between the nozzle and the locality, the laws supply a gap of the criterion Strength Calculation of Pressure Parts for Watertube Boilers. |
