| Popis: | A stabilized Isogeometric formulation of compressible flows is coupled to a large-deformation inelastic solid with an M7 Microplane constitutive model of concrete failure discretized in the framework of correspondence-based Peridynamics with bond-associated stabilization. The fluid–structure interaction (FSI) coupling makes use of a simple volumetric penalty technique that enables effective handling of the solid fracture and fragmentation. The capabilities of the FSI framework presented are demonstrated, in 3D, for point-charge detonation on concrete slabs. Slabs of varying thicknesses are simulated to capture the typical behavior of concrete under blast loading scenarios. |
