“…EI-Salakawy et al [10] reported that concrete bridge barriers with glass-fibre-reinforced polymer (GFRP) bars show similar behaviour with conventional steel-reinforced barriers in strength, cracking and energy absorption under pendulum impact test. Teng et al [11] proposed a model to evaluate impact resistance of reinforced concrete using finite element analysis. Badr et al [12] reported statistical variations in impact resistance of polypropylene fibre-reinforced concrete.…”

“…Options based on von Mises theory (e.g., effective stress, effective strain, effective plastic strain) are well suited for isotropic materials like metals (e.g., steel, copper, iron) (e.g., Kurtaran et al [9], Fawaz et al [10]). For anisotropic materials (e.g., concrete, orthotropic material), parameters such as principal stress and principal strain have been employed (e.g., Schwer [11], Teng et al [12], Islam et al [13]).…”

Close-in detonations can damage or destroy components of buildings. The damage to reinforced concrete components is often simulated using finite element codes with considerations of material erosion that are based on either a damage algorithm or a user-specified criterion, and both are explored in the paper. Single element simulations of concrete are performed to establish reliable values of concrete erosion strain as a function of strain rate, compressive strength, element size and loading condition. Numerical analyses of a reinforced concrete column subjected to blast loadings are performed using alternate representations of erosion to characterize the influence of concrete compressive strength, transverse reinforcement, and applied axial load, on predictions of damage.

“…The results demonstrate that adding fibers enhances impact resistance by 4-15 times that of the plain slab without fibers, and coir fiber outperforms the other four fibers. Teng et al( 2004) established a finite element analysis based methodology for evaluating the impact response of RC slabs. Dancygier et al (2007) investigated the behavior of high-strength concrete plates to non-deforming bullet impact.…”

In this research work, different combinations of normal strength concrete (NSC), ultra-high-performance concrete (UHPC), and steel fiber-reinforced UHPC (SFR-UHPC) concrete with re-bars of conventional steel and of carbon fiber-reinforced polymer (C-FRP) are used in a two-way square slab of size 1000mm x 1000mm x 75mm subjected to 2500 mm free-fall impact loading. Experimental arrangement consisting of 105 kg dropping weight with the circular flat impacting face of 40 mm diameter used for carrying out impact test is modeled using a high-fidelity physics-based finite element computer code, ABAQUS/Explicit-v.6.15. After validating the experimental results of the NSC slab with steel bars, analyses are extended by replacing NSC and steel bars with UHPC/SFR-UHPC and C-FRP bars, respectively, under the same dropping weight. Only the remote face (tension face) of the slabs is provided with the re-bars. Widely employed and available with the ABAQUS, the Concrete Damage Plasticity model with strain-rate effects has been entrusted for simulating the concrete plastic response. Re-bars of steel are idealized with the Johnson-Cook plasticity damage model. C-FRP re-bars are defined with the classical plasticity model following the elastic-plastic constitutive laws. The impact responses of the slabs consisting of NSC/UHPC/SFR-UHPC concrete with re-bars of steel, and C-FRP combinations considered are discussed and compared. Slabs made of UHPC/SFR-UHPC concrete with the C-FRP re-bars are found to offer a promising combination of materials to withstand low-velocity impact load with little damage and extraordinary impact performance.
