In this study, the blast performance of steel reinforced concrete (RC) beams was experimentally and analytically investigated. The experiment consists a total 10 one-half-scale subjected to different levels loading using live explosives. reflected pressure-time histories were recorded damage modes observed. resilience damaged quantified by measuring time-dependent displacements. Experiment results show that in with higher explosive mass is enhanced compared smaller at same scaled distance....
Understanding human behavior and society is a central focus in social sciences, with the rise of generative science marking significant paradigmatic shift. By leveraging bottom-up simulations, it replaces costly logistically challenging traditional experiments scalable, replicable, systematic computational approaches for studying complex dynamics. Recent advances large language models (LLMs) have further transformed this research paradigm, enabling creation human-like agents realistic...
Although polyurea has attracted extensive attention in impact mitigation due to its protective characteristics during intensive loading, the ballistic performance of polyurea-reinforced ceramic/metal armor remains unclear. In present study, with different structures was designed, including three types coating positions polyurea. The tests were conducted a gun; samples subjected tungsten projectile formed into cylinder 8 mm diameter and 30 length, deformation process tested targets recorded...
Combined use of ultrahigh-performance concrete (UHPC) with glass fiber reinforced polymer (GFRP) reinforcement has the potential for further blast resistance enhancement (RC), due to improved toughness UHPC and high strength-to-weight ratio GFRP. This paper aims fill gap on effectiveness GFRP bars response beams. The beams built (UHPC-GFRP beams) is experimentally numerically investigated in this paper. In experimental scheme, twelve strengthened various types are tested under near-field...
Abstract Limited research has been carried out to investigate the local damage features of reinforced concrete (RC) beams under close‐in explosions. To better capture rectangular cross‐sectional RC beams, a numerical study on subjected explosions based calibrated Karagozian & Case (K&C) model was conducted in LSDYNA. First, systematic calibration K&C for performed single‐element analysis. Calibration consists parameter determination new strength surfaces, modification function...
The majority of the projectiles used in hypersonic penetration study are solid flat-nosed cylindrical with a diameter less than 20 mm. This aims to fill gap experimental and analytical evolution nose shape larger hollow under penetration. In test, eight ogive-nose AerMet100 steel 40 mm were launched hit concrete targets impact velocities that ranged from 1351 1877 m/s. Severe erosion was observed during high-speed heterogeneous targets, apparent localized mushrooming occurred front recovered...
This paper presents the results of an experimental investigation on explosive breaching p-section concrete beams. Twenty three beams with a 100 cm length were tested. TNT charges placed at positions: contact detonation in center, above web and close-in center. The external internal breach parameters panels evaluated by measuring diameter ejection crater, spalling crater hole created charge detonation. compared to predict values obtained analytical models proposed McVay, Morishita Remennikov....
