Study on Coercivity-Stress Relationship of X80 Steel under Biaxial Stress

, 2022
Buried pipelines are prone to deformation under surface displacement, pressure occupation, and/or other actions, resulting in stress concentration. Conducting regular stress detection is an important approach to reducing pipeline accidents.
