A corrected transport velocity formulation (CTVF) based solver is developed to study the deformation of elastic structures under hydrodynamic loads. CTVF is adopted to handle both fluid and structural dynamics. The current solver’s advantage is to eliminate inhomogeneous particle distribution in fluid flow and tensile instability in elastic structures. A ghost particle-based approach is used to handle the coupling between the fluid and solid phases. The proposed scheme is verified by simulating a few test cases, which we validate with exact analytical solutions. As an application, we simulate an elastic plate deformation due to dam-breaking fluid.
