RISCombined Effects of Tube Projection, Initial Tube-Tubesheet Clearance, and Tube Material Strain Hardening on Rolled Joint Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tube-to-tubesheet joint strength is measured in terms of interfacial pressure between the tube’s outer surface and tubesheet bore. The strength of a rolled joint is influenced by several ...
Modeling the Effects of Initial Tube-Tubesheet Clearance, Wall Reduction and Material Strain Hardening on Rolled Joint Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tube-to-tubesheet joint strength is measured in terms of residual contact pressure between the tube’s outer surface and tubesheet hole surfaces. The joint integrity is affected by several ...
Residual Stresses in Roller Expanded Tube-Tubesheet Joints With Large Initial Clearance and Grooves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat exchanger tube rolling introduces tensile residual stresses in the expanded part of the tube and the transition zone between the expanded and unexpanded regions of the tube. These tensile ...
