Study of Tensile Deformation and Damage Law in Undermatching X80 Pipeline Steel Welded Joints

This study used a digital imaging technique (DIC) to obtain the strain distribution at various locations in undermatching X80 pipe girth-weld joints under uniaxial tensile loading. In addition, the microstructure characteristics and deformation patterns in different regions were analyzed by scanning...
