Load–slip curves of screwed joints. Black line curves obtained yield load using 3 points on the curves corresponding to 10, 40, and 90% of the maximum load; red line curves obtained yield load using 3 points on the curves corresponding to 10, 60, and 80% of the maximum load; solid line curves of specimens with a width of 60 mm; broken line curves of specimens with a width of 45 mm
