    Fatigue Behaviors of Thick Cruciform Joints Made by Q355D Structural Steel Under Different Post-Welding Treatments

    Wei Song1,*, Xiaojian Shi2, Shoupan Wei2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.30, No.3, pp. 1-1, 2024, DOI:10.32604/icces.2024.012236

    Abstract Different post-welding treatments, such as TIG-Dressing, blinding, HFMI et.al are often used for steel welded joints in construction machinery manufacturing as an effective and reliable method for fatigue strength improvement. This paper investigates the fatigue performance of thick Q355D cruciform joints in heavy load-carrying steel structures under different treatments. Two TIG-Dressing treatments, blinding and HFMI for the full-penetration welded joints were used for fatigue tests. Experimental tests studied the fatigue strength of cruciform welded joints of Q355D structural steel under different treatments. The geometric parameters and relevant statistical analyses were performed by actual 3D optical More >

    Finite Element Analysis of Three-dimensional Periodic Notched Plates

    R. Afshar1, F. Berto1,2

    Structural Durability & Health Monitoring, Vol.9, No.4, pp. 349-364, 2013, DOI:10.32604/sdhm.2013.009.349

    Abstract Using the finite element method, three-dimensional models of a number of periodic blunt and sharp notches subjected to tension loading are carried out. The aim of this research is to investigate the thickness effect on the location of maximum stress and notch stress intensity factor (NSIF) of corresponding blunt and sharp periodic notches respectively. With this aim, a wide range of notch geometries are examined. While for two-dimensional plates weakened by periodic notches some results are available in the literature, this paper first faces with the problem of three-dimensional cases. The total of about 100 More >

    Some Recent Developments on the Application of the Strain Energy Density to Shallow Threaded Plates with Sharp Notches

    R. Afshar1, F. Berto1

    Structural Durability & Health Monitoring, Vol.9, No.2, pp. 167-180, 2013, DOI:10.32604/sdhm.2013.009.167

    Abstract In this study, the main advantages of the strain energy density (SED) approach and some recent applications of the SED to the fatigue analysis of welded joints are reviewed. In addition, the paper investigates the scale effect in the threaded plates with sharp notches subjected to tension loading. Some closed form expressions for evaluation of the notch stress intensity factors (NSIFs) of periodic sharp notches, obtained by SED approach, are employed. The new expressions are applicable to narrow notches when the ratio between the notch depth and the plate width, t/W, is lower than 0.025 More >
