Published in 2017 at "Engineering Fracture Mechanics"

DOI: 10.1016/j.engfracmech.2017.04.039

Abstract: Abstract Structural integrity assessment of weldments requires the input of flow stress-strain curve of each individual material zone. To cope with these challenges, a cylindrical cross weld tensile specimen with a notch located either in… read more here.

Published in 2020 at "Structures"

DOI: 10.1016/j.istruc.2020.10.002

Abstract: Abstract Wrapping reinforced concrete (RC) column with FRP sheets enhances compressive strength and ductility of column. Since stress–strain curve of FRP-strengthened concrete is different from stress-strain curve of normal (un-strengthened) concrete, relations presented by codes… read more here.
