The Fatigue Strength of Fillet Welded Connections
This report describes a study of the fatigue behavior of fillet welded joints stressed perpendicular to the weld line. The study included an experimental phase in which the stiess-life and cracking behavior of load and nonload carrying fillet weld joints was determined. This experimental study concentrated on the fatigue behavior in the transition region between high and low cycle fatigue 3 5 (...
متن کاملFatigue Strength of Fillet-Welded Transverse Stiffeners with Undercuts
Presently, wrapping of the welds at the ends of stiffeners is not done to avoid the undercutting of the stiffener corners and the attendant weld repair. The fatigue performance of stiffeners with undercuts was evaluated in a factorial design fatigue experiment. Undercuts at the flange edge and filling of the stiffener cope with the fillet weld were also evaluated. The undercuts did not influenc...
متن کاملImproving Fatigue Strength of Welded Joints by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated with large-scale rolled beam and built-up specimens having yield strength of 345 to 760 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating t...
متن کاملFinite Element Analysis of Effect of Weld Toe Radius and Plate Thickness on Fatigue Life of Butt Welded Joint
Mechanical parts during service may be subjected to cyclical loading and high stresses, which make fatigue life prediction extremely important. The finite element method is commonly used in research institutions and industry in order to estimate life span of mechanical parts. In this study, an experimental investigation of the geometrical dimensions and mechanical properties of a weld joint, an...
متن کاملThe Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel
The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...
