External damage and repair of a gas transmission pipeline were often encountered in industrial production. The damage of the gas transmission pipeline and the evaluation after repair could be solved by the finite element simulation method. Damage assessment and postrepair assessment were carried out for an external damage example of a gas transmission pipeline in an oil field based on finite element software ABAQUS. Ideally, the finite element simulation results were modified by using thedoi:10.1155/2022/3978649 fatcat:ge55ffvav5ef5gqzlncdmhlx44
