Outline of Research at the Start

This research will present the first entirely Lagrangian meshfree FSI solver for comprehensive structural responses including viscoelasticity and plasticity, in both 2D/3D, and with multi-physics air-water-structure interactions. Due to its Lagrangian meshfree features, variationally consistent extensions of structure model and multi-physics interactions, the solver is expected to provide reliable results in ocean/coastal structure design, especially in extreme events.
