  31. <meta content="Fatigue may occur in undercarriages and support systems of trailers, haymakers, graders and swing-ploughs made up
  32. of thin-walled tubular sections with wall thicknesses less than 4mm. Little research has been done on the fatigue of
  33. thin-walled tubular sections below 4mm thickness. The weld profile and weld undercut may affect the fatigue crack
  34. propagation life of welded joints especially for thin-walled sections. Numerical analysis of 2-dimensional non-load
  35. carrying thin-walled cruciform joints was performed to determine the effect of weld profile and weld undercut on
  36. fatigue crack propagation life under cyclic tensile loading. The cruciform joints analysed are made up of 3mm thick
  37. plates, joined by fillet welds. The Boundary Element Analysis System Software (BEASY) is used, which uses
  38. fracture mechanics theory to carry out crack propagation analysis. The weld profiles and weld undercuts were
  39. measured from welded connections in thin-walled fillet welded sections. The measured weld profiles and undercut
  40. were used in the analysis. The results are compared with those of a similar study to determine the comparative
  41. reduction in fatigue crack propagation life between thin-walled cruciform joints (T=3mm) and thicker walled
  42. cruciform joints (T=20mm). This paper provides an understanding of the impact which weld toe undercut has on the
  43. fatigue crack propagation life of thin-walled cruciform joints. The presence of undercuts may reduce the benefits of
  44. the thickness effect in thin-walled joints of thicknesses less than 4mm." name="eprints.abstract" />

  285. of thin-walled tubular sections with wall thicknesses less than 4mm. Little research has been done on the fatigue of&#13;
  286. thin-walled tubular sections below 4mm thickness. The weld profile and weld undercut may affect the fatigue crack&#13;
  287. propagation life of welded joints especially for thin-walled sections. Numerical analysis of 2-dimensional non-load&#13;
  288. carrying thin-walled cruciform joints was performed to determine the effect of weld profile and weld undercut on&#13;
  289. fatigue crack propagation life under cyclic tensile loading. The cruciform joints analysed are made up of 3mm thick&#13;
  290. plates, joined by fillet welds. The Boundary Element Analysis System Software (BEASY) is used, which uses&#13;
  291. fracture mechanics theory to carry out crack propagation analysis. The weld profiles and weld undercuts were&#13;
  292. measured from welded connections in thin-walled fillet welded sections. The measured weld profiles and undercut&#13;
  293. were used in the analysis. The results are compared with those of a similar study to determine the comparative&#13;
  294. reduction in fatigue crack propagation life between thin-walled cruciform joints (T=3mm) and thicker walled&#13;
  295. cruciform joints (T=20mm). This paper provides an understanding of the impact which weld toe undercut has on the&#13;
  296. fatigue crack propagation life of thin-walled cruciform joints. The presence of undercuts may reduce the benefits of&#13;
  297. the thickness effect in thin-walled joints of thicknesses less than 4mm.</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;
