Анизотропная ползучесть многопроходного шва

Abstract

A method of evaluating creep response of the multipass welding based on the micro-macro mechanics approach is introduced. Creep material properties for equivalent weld material by known properties of weld metal grain type zones are found. As an example of macro model analysis of the welding, the creep calculation of the tube with the welding under the uniform pressure on the inner bounds was performed.
