Test method for constitutive relationship of pipeline girth welds based on notched round bar specimens

To accurately obtain the true constitutive relationship of each material area in the girth welds of high-strength pipeline steel. Definitely, two kinds of notched round bar specimens were obtained by setting notches on the base metal and in the weld area of X80 steel respectively, and the tensile te...
