The effect of HTD on yarn parameters was analyzed by using SPSS. The results show that HTD has significant influence on parameters of thickness fault and nep. As a whole, the HTDs of 0.42 and 0.56 mm are beneficial to improving yarn quality in comparison with the other HTDs.展开更多

In this paper, the effect of weld geometry on fatigue failure of load carrying cruciform joints inships is investigated using Effective Notch Stress (ENS) approach. A fictitious notch of 1 mm radius is introduced at theweld root and toe and fatigue stress is evaluated. The effect of weld leg length (l) and weld penetration depth (p) on ENS atweld root and toe are determined. The critical weld leg length (lcr) at which fatigue failure transitions from weld root toweld toe is investigated. An approximation formula for determination of the critical weld leg length considering weldpenetration depth (p) is proposed.展开更多
