Deformation and Fracture of Welded Tee-Joint in Cylindrical Storage Tank

Correlation of Energy, Deformation and Fractographic Parameters of Microalloyed Steel Welded Joint Fracture

Toughness is a complex material characteristic that is viewed from multiple aspects and is influenced by numerous factors. It is very important to have ability to assess toughness, i.e. to determine ductile or brittle material behaviour at any specific time. Beside total impact energy obtained at Charpy instrumented pendulum, the use of additional parameters such as lateral extension measuremen...

Fracture Assessments of Welded Structures

Weldments are particularly susceptible to fracture due to defects, material property variations, and residual stresses created during the welding process. It is common in fracture assessments of welded structures to ignore these features; defects are often idealized to be crack-like, weld properties to be homogeneous, and residual stresses to be uniaxial and tensile or nonexistent. This paper p...

Azimuthal solitary surface wave in cylindrical tank.

This Brief Report is devoted to the study of the solitary surface wave rotating in the azimuthal direction, arising during water drainage from a cylindrical reservoir, when shallow flow conditions are reached. The linear dependence between the wave speed and its amplitude is shown to be similar to that expected from the classical Korteweg-de Vries equation.
