Large displacements of light thin flexible structures coupled with heavy fluids using co-simulation between finite element and fast boundary element solvers

Résumé

This work deals with the dynamic analysis of an immersed circular cylinder, stiffened at its extremities, with a membrane-like behavior subjected to an axial force and fluid-structure interaction loadings. The membrane density and the fluid density are of the same order, hence the added mass effect is significant and the physical coupling is strong. The solution is computed by means of a co-simulation procedure between ABAQUS R©/Standard to solve the structural sub-problem and an in-house potential flow code based on boundary integral formulations, to solve internal and external fluid sub-problems. The space coupling, i.e. field spatial mapping and field exchanges at the fluid-structure interface, and the time coupling, i.e. time synchronization of fluid and structure solvers, are performed using SIMULIA R© Co-Simulation Engine. The strong numerical coupling is enforced by using efficient iterative algorithms.
