Abstract

This study aims to analyze Whitworth thread's fatigue characterization due to dynamic twisting on low carbon steel. The research method uses experiments with pre-experimental design with the form of intact group comparison. The experimental group was specimens with Whitworth thread notch depth of 0.67 mm, 0.81 mm, and 1.16 mm. The control group was Whitworth threads with a notch depth of 0.9 mm. The study used low carbon steel with a carbon content of 0.12% wt. The dynamic torsion testing with a twisting angle of 5 reveals that the deeper the Whitworth thread notch, the lower the fatigue resistance. The fracture surface is visible due to dynamic torsion in the form of initial crack, crack propagation rate, and final crack
