The mechanism of failure of heat exchanger and steam generator tube-to-tubesheet joints is related to the level of residual stresses produced in the tube expansion and transition zones during the expansion process and their variation during operation. The accurate prediction of these stresses based on the plastic and creep properties of the joint materials involved can help to design ... https://zskfxu1o3qqg.blog2freedom.com/34909770/career-stability-in-14-finnish-industrial-employee-cohorts-in-1988-2015
