| Abstract: | By the finite element analysis of three-way pipe,the accurate stress distribution characteristic was obtained under the inner pressure.An assess of stress intensity was made based on ASME Ⅷ-Ⅱ《America pressure vessel criterion analysis》.The engineering application showed that the finite element analysis software was good at solving the equipment large opening,especially solved the stress calculation of pipe hole borne complex external load of pipeline. |
