  29. <meta content="Welded thin-walled (t<4mm) tube-to-plate T-joints made up of cold-formed circular hollow sections welded onto a
  30. plate to form a moment resistant connection are used in the road transport and agricultural industry to manufacture
  31. equipment and other structural systems. Fatigue design of these joints is not available in current standards. An
  32. understanding of the stress concentrations and failure in these connections is therefore necessary as a step towards
  33. understanding the fatigue behaviour of these connections. Stress concentration factors (SCFs) of welded thin-walled
  34. (t<4mm) circular hollow section (CHS)-to-plate T-joints are determined at different locations along the weld toes on the
  35. tubular brace. The distribution of SCFs along the weld toes shows that the highest SCF occurs at the weld toes in the
  36. circular brace at the 0o line. The ratio of the end of test fatigue life (N4) to the through thickness fatigue life (N3) in the thin CHS-Plate T-joints is found to fall within the range of N4/N3 found in previous research of both thick and thin-walled joints. Surface crack growth monitoring is used to obtain an approximation of the length of surface crack at the point of occurrence of a through thickness crack. The relationship between surface crack length and the occurrence of a through thickness crack is important in that it can be used as a measure of the criticality of a surface crack during structural health monitoring of equipment or structures." name="eprints.abstract" />

  245. plate to form a moment resistant connection are used in the road transport and agricultural industry to manufacture&#13;
  246. equipment and other structural systems. Fatigue design of these joints is not available in current standards. An&#13;
  247. understanding of the stress concentrations and failure in these connections is therefore necessary as a step towards&#13;
  248. understanding the fatigue behaviour of these connections. Stress concentration factors (SCFs) of welded thin-walled&#13;
  249. (t&lt;4mm) circular hollow section (CHS)-to-plate T-joints are determined at different locations along the weld toes on the&#13;
  250. tubular brace. The distribution of SCFs along the weld toes shows that the highest SCF occurs at the weld toes in the&#13;
  251. circular brace at the 0o line. The ratio of the end of test fatigue life (N4) to the through thickness fatigue life (N3) in the thin CHS-Plate T-joints is found to fall within the range of N4/N3 found in previous research of both thick and thin-walled joints. Surface crack growth monitoring is used to obtain an approximation of the length of surface crack at the point of occurrence of a through thickness crack. The relationship between surface crack length and the occurrence of a through thickness crack is important in that it can be used as a measure of the criticality of a surface crack during structural health monitoring of equipment or structures.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available at http://www.sciencedirect.com&#13;
