Abstract

Mechanical damage, caused by mechanical forces that deform the natural cylindrical shape of a pipe, can be detrimental to the operational integrity of a pipeline. Mechanical damage can either remain benign for the operational life of the pipeline or lead to failure. Mechanical damage is the leading cause of pipeline failures in the United States. Therefore, it is important to both detect mechanical damage defects and characterize parameters such as microstructure change, residual stress, and the extent of removed metal.
