The 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...

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 کاملThe Ballistic Behavior of High Strength, Low Alloy-100 Steel at Sub-zero Temperatures
The ballistic response of the high strength, low alloy (HSLA-100) steel at ambient and temperatures of -400°C, -800°C and -1960°C is investigated in this work. Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt ti...
