  We present a novel formulation for the immersed coupling of Isogeometric
Analysis (IGA) and Peridynamics (PD) for the simulation of fluid-structure
interaction (FSI). We focus on air-blast FSI and address the computational
challenges of immersed FSI methods in the simulation of fracture and
fragmentation by developing a weakly volume-coupled FSI formulation by means of
a simple penalty approach. We show the mathematical formulation and present
several numerical examples of inelastic ductile and brittle solids that clearly
demonstrate the power and robustness of the proposed methodology.
