Unified solution algorithm for solids and fluids

In this work, we propose a new unified-solution algorithm for solids and fl uids using generalized simplified marker and cell (GSMAC)-finite element me thod (FEM). We use the Lagrangian description for displacement vector field s in solids, and, the Eulerian description for velocity vector fields in fl uids. We carried out the analysis for static beam bending problems and dyna mic viscoelastic response problems in order to the verify the validity of t he present scheme for the solid phase. Additionally the analysis of self-ex cited oscillations of a cylinder in uniform flow is performed as a coupled vibration problem between the fluid and solid.
