Abstract
The study compares performances of numerical finite element (FEM) analyses of simply supported concrete slabs reinforced by BFRP bars (basalt fibre reinforced polymer) exposed to close-range (1 m distance) explosions. A sensitivity study of slab deflection and reinforcement strain on various shapes of TNT charges is conducted. Smoothed-particle hydrodynamics (SPH) method is used to model the geometry of the TNT charges (variously rotated cylinders, cubes and spheres), detonation and interaction with the concrete slab, which is modelled by Lagrangian mesh. Karagozian and Case (K&C) nonlinear material model is used for concrete slabs exposed to high-velocity impact load. Finite element analyses have been conducted in explicit solvers suitable for high strain rates. The results of numerical simulations are compared with physical experiment data obtained from the scientific literature.
