In order to protect the reinforced concrete (RC) slab structure from damage under some accidental conditions, such as impacting and explosion, we used bio-inspired honeycomb column thin-walled structure (BHTS) to serve as a buffer interlayer for the concrete structure inspired by the biological structure of beetle’s elytra. The mechanical properties of AlSi10Mg used to fabricate the BHTS buffer interlayer were determined by low- and medium-speed uniaxial compression tests and numerical simulations. Subsequently, based on the drop weight impact test models, the effect of the buffer interlayer on the response of the RC slab under the drop weight tests with different energy input was compared by the impact force and duration, maximum displacement and residual displacement, energy absorption (EA), energy proportion, and other indicators. The results show that the proposed BHTS buffer interlayer has a very significant protection effect on the RC slab under the impact of the drop hammer. Due to its superior performance, the proposed BHTS buffer interlayer provides a promising solution for EA of augmented cellular structures widely used in defensive structural components, such as floor slabs, building walls, etc.

“…LS-DYNA® element library provides different types of element formulations based on the different types of integration methods. The type of element formulation required is The total clock time for simulations using the two different element formulation was, 32 minutes with normal termination for ELFORM = 1 and it was 240 minutes with error The negative volume effect which is dominant in the fully integrated S/R solid elements (ELFORM=2) subjected to large deformation causing instabilities and error terminations can be overcome by using constant stress solid elements [21]. But the reduced integration formulation can cause no straining at the integration points thus leading to deformation modes called zero-energy modes or "hourglass modes".…”

“…The HGEN variable in *CONTROL_ENERGY is set to type 2 for computation of hourglass energy and inclusion in the energy balance [4]. The non-physical hourglass energy should be small relative to the peak internal energy (< 10% as rule of thumb) for confirming the effectiveness of hourglass control [21]. Remennikov and Kong performed numerical simulation of the response of non-composite steel-concrete-steel sandwich panels where they reported hourglass energy up to 50% of its peak internal energy when the effects of strain rate were considered in the simulation.…”

“…Remennikov and Kong performed numerical simulation of the response of non-composite steel-concrete-steel sandwich panels where they reported hourglass energy up to 50% of its peak internal energy when the effects of strain rate were considered in the simulation. They recommended exclusion of strain rate effects to minimize the hourglass energy as that reduced it to 15% of internal energy [21].…”

The work done in this research is to study the response of reinforced concrete slabs subjected to blast loading as they can be used as protective structures around the main structure. An experimental investigation has been performed in a separate study involving blast-testing of 12 reinforced concrete slabs in a shock tube (Blast Load Simulator). The data from this experimental investigation was made available for performing advanced finite element analysis done in this research to study the behavior of these slabs towards blast loading.A non-linear transient dynamic finite element analysis program LS-DYNA® is used for this study. The finite element models of these 12 slab panels are developed in LS-DYNA® and blast pressures equivalent to those generated in the experiment are applied to them. These slabs include two material combinations based on their strength namely, the high-strength concrete reinforced with high-strength steel slabs and normal-strength concrete reinforced with normalstrength steel slabs. The primary objective is to study the response of material combinations to blast loading by using two different concrete material models available in LS-DYNA namely, Winfrith Concrete Model and Concrete Damage Model Release 3 and comparing it with the experimental results. Validation of these models with experimental data will provide a iv numerical analysis procedure which will be less expensive and safer than performing blast testing.On performing this study, finite element analysis and experimental validation of reinforced concrete single-mat slabs subjected to blast loading it is concluded that the Winfrith Concrete Model predicts a better response in terms of deflection and crack propagation for both normal and high strength concrete. Concrete Damage Model Release 3 needs additional parameters to be defined based on concrete laboratory testing data for it to predict a better response in the normal-strength and high-strength category. These additional parameters have been developed and recommended in this study.

“…They validated their results with experimental data and observed that the failure mode shifts from penetration to perforation by increasing the blast charge amount. Kong et al [7] performed a numerical investigation non-composite SCS panel without a shear connector. They proposed a novel detailing for flared end connections to eliminate relative movement between the concrete core and the steel plates through axial restraint.…”

The safety of the civil structures could be significantly improved against shock waves and blast loads by using steel concrete steel (SCS) protective walls. A numerical study has been performed to simulate the response of SCS wall subjected to a near-field blast load. A conventional SCS panel subjected to near-field blast load and its structural performance is evaluated in terms of maximum damage and deformation. The simulations performed using ABAQUS\EXPLICIT finite element package and built-in concrete damage plasticity concrete constitutive formulation. The maximum deformation, plastic strain, and failure mode under different loading scenarios have been investigated. The aim of this study is predicting the structural response of the SCS panel with different blast charge and identification of optimum configuration in terms of concrete strength and plate thickness. In the second part of the study, two novel sandwich configurations consisting of a corrugated metal sheet and the concrete core are proposed and compared with the conventional protective walls. The optimum parameters for each structural component are identified using an optimization procedure. Based on this study, using the proposed wall configuration will results in superior performance compared to the conventional walls while the extra cost of fabrication is insignificant.
