The paper presents an enhanced fully-Lagrangian coupled solver for simulations of fluid-structure interactions. The solver is based on Moving Particle Semi-implicit (MPS) method which solves the governing equations corresponding to incompressible fluid flows as well as elastic structures and includes a consistent coupling algorithm. The presented model is an enhanced version of a previously developed FSI solver which benefits from a newly incorporated set of enhanced schemes for the fluid model as well as a refined calculation of fluid force to structure. The enhanced performance of the proposed solver is verified by reproducing a high velocity impact of a deformable aluminum beam on undisturbed water as well as a dam break with an elastic plate.
