Analysis of Tube-Tubesheet Joint Loading Including Thermal Loading

Abstract

The tube-to-tubesheet rolling process is reexamined using a two-dimensional elastic plastic analysis. In addition to room temperature rolling, subsequent thermal cycling of the joint is considered. The development of a computer code based on an incremental analysis that includes finite deformation effects and the possibility of reversed yield is presented. Typical simulations are presented that indicate some of the influences of geometry, materials, and loading on final tube-to-tubesheet contact pressure.
