Analysis on collapse behavior of sandwich pipelines considering the eccentric effect

Compared with the traditional single-layer pipelines, the sandwich pipelines have a more complex structural configuration, and the problem of non-uniform filling thickness in the sandwich layer may occur easily in the manufacturing process, which could result in the decentraction of the inner and ou...
