Mode shape remains vital in dynamic analysisof the structures. It can be utilized in failure analysis, and the dynamic interaction between structures and their supportsto circumvent abrupt failure. Conversely, unlike empty pipes, the mode shapes for pipes conveying fluid are tough toobtain due to the intricacy of the eigenvectors.

Thus, due to their global functions, their dynamic and failure analyses are necessary for monitoring theirreliability to avert catastrophic failures. In this work, three techniques for obtaining approximate mode shapes (AMSs) of composite pipes conveying fluid, their transition velocity and relevance in failure analysis were investigated.
