“…It has been widely used to model the responses of concrete structures subjected to impact and blast loads, and proved yielding reliable numerical predictions [51][52][53][54][55]. The default parameters in *Mat_072R3 model are based on conventional OPC tests [56,57]. However, *Mat_072R3 with specific material parameters has been used to model ultra-high performance concrete (UHPC) [57], hybrid-fibre engineered cementitious composites [58], and ultra-high performance fibre reinforced concrete (UHPFRC) [59] under impact and blast loads.…”

“…The investigated UHPC was prepared with a low cement content of 252 kg/m 3 and binder content of 574 kg/m 3 to enhance material unit cost. The cement content was much lower than the 889 kg/m 3 used by [31,32] and 450 kg/m 3 used by [33]. The composition of UHPC followed the parameters reported by [34].…”

This study assesses the ballistic impact strength of thin plates made of ultra-high-performance concrete (UHPC) with low cement content (250 kg/m3) and volumes of 80% steel and 20% polypropylene (PP) hybrid fibers. The plates were prepared with thicknesses of 30, 50, and 70 mm and fiber volume ratios of 1.5% and 3.0%. Compressive strength, flexural tensile strength, residual strength, and ballistic impact strength were determined using experimental methods. Test results showed that regardless of fiber content, the UHPC specimens prepared with the hybrid fibers showed similar performance against ballistic impact, exerting relatively low impact energy below 1000 J. The UHPC3.0 mixture made with 3.0% hybrid fiber content exhibited the best performance in terms of energy absorption and spalling resistance at impact energy levels greater than 4000 J. Plate sections with thicknesses of 7 mm showed class III performance (highest level), as recommended for military-based applications.

“…The erosion criterion in the FEM is one of major parameters used in these types of analyses. The erosion criterion usually depends on the researcher’s empirical decisions, and various values of the erosion criterion have been proposed by many researchers (Liu et al., 2017; Li and Zhang, 2012). In order to reduce the element size sensitivity of the FEM as mentioned in section 3.3, a sensitivity study of the pure FEM model is conducted by calibrating the erosion criterion according to the element size.…”

This paper presents a projectile impact analysis of high-performance fiber-reinforced cement composite (HPFRCC) structures based on the coupling of the finite element method (FEM) and the smoothed particle Galerkin (SPG) model in the LS-DYNA program. The K&C material model is calibrated for the HPFRCC. Through a quasi-static analysis using the calibrated model, the criteria for the element size of a FEM and the nodal particle distance of the SPG model are determined. Numerical simulations of the coupled SPG-FEM model are conducted to predict the structural responses of HPFRCC structures subjected to high impact velocities ranging from 342 m/s to 808 m/s. The results for the coupled model are compared with experimental data as well as numerical results for a pure FEM model to determine the relative accuracy and efficiency of a coupled FEM and SPG model for the large deformation problem. The convergence of the numerical results is also investigated in terms of the residual velocity and penetration depth. Moreover, the effects of various parameters on the models are discussed through a sensitivity analysis, and suitable parameter ranges that improve the accuracy of the numerical results are suggested.
