National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Crack Growth Behavior in Residual Stress Field in Vessel Type Structures.

DE2004808878

Publication Date	2004
Personal Author	Dong, P.; Zhang, J.
Page Count	24
Abstract	Detailed residual stress analysis was performed for a multi-pass butt weld, representing the middle butt-girth weld of a storage tank. The analysis procedures took into account representative welding parameters, joint detail, weld pass deposition sequence, as well as temperature-dependent properties. The predicted residual stresses were then considered in stress intensity factor calculations using a three-dimensional finite element alternating model (FEAM) for investigating crack growth behavior for both small elliptical surface and through-wall cracks.
Keywords	Risidual stress Storage tanks Welds Structural analysis Crack propagation Analysis Procedures Crack growth Cracking (Fracturing) Fracture mechanics Finite element alternating model (FEAM)
