In the end, a novel algorithm for coupling the fluid and solid subproblems is presented. The framework is supplemented with a phase-field model of brittle fracture that allows for the simulation of crack nucleation, propagation, and branching, which leads to realistic modeling of structural responses during extreme hydrodynamic events. The meshfree nature of the discretization technique accommodates the simulation of scenarios involving extreme structural deformations and material separation, as well as free-surface flows. ![]() The smoothed particle hydrodynamics (SPH) approach is employed to discretize the equations of motion for both the fluid and structural domains. We present a proof-of-concept particle-based fluid–structure interaction (FSI) computational framework for modeling structural fracture and fragmentation under the impact of extreme hydrodynamic events.
