Abstract

Abstract

A finite element calculation method for stress Indices based on stress Indices definition in RCC-M standard is presented.A finite element model for vertical branch pipe connection is established by the finite element analysis software ANSYS,to calculate the stress indices of branch pipe connection.The effectiveness of the calculation method for stress indices is verified by comparing with the stress indices of branch pipe connection specified in RCC-M.
