Abstract The performance of drop hammer tear test and pendulum impact test of pipeline steel are two important parameters of materials, which can help determine the safety and reliability of materials or products. Two pipeline steel samples with different specifications and different properties were used to perform drop hammer tear test and Shaabi pendulum impact test at different temperatures. The impact shear section rate and the drop hammer shear area fraction in two test methods were compared. The difference and relationship were studied based on the test results. The results showed that the change laws of impact shear section rate and the drop hammer shear area fraction were basically consistent during the temperature variation for two pipeline steel samples with different specifications and different properties in drop hammer tear test and pendulum impact test.

Key words： drop hammer tear test pendulum impact test impact shear section rate drop hammer shear area fraction
