Effect of Ovality Length on Collapse Strength of Imperfect Sandwich Pipes Due to Local Buckling

Effect of Ovality Length on Collapse Strength of Imperfect Sandwich Pipes Due to Local Buckling

The effect of ovality length on imperfect sandwich pipes is investigated using the finite element method in the scenario of local buckling under external pressure. First, the finite element model of the imperfect sandwich pipelines is established in ANSYS and is validated by comparing the results fr...
