WebAs described in Krisanski et al. (Citation 2024), the resampled five plots were divided into training, validation, and test sets (0.5/0.25/0.25) at the plot level to ensure that the representative samples of each point cloud were present in the training, validation, and test sets. After the split, the datasets of the five plots were put together to train a model. WebThe benchmark problems selected are a Taylor cylinder test, a split Hopkinson pressure bar test, a free air blast, the dynamic splitting tension (Brazilian) test, and projectile penetration of a concrete slab. ... High strain-rate measurements were performed on specimens of advanced cellular materials with predefined structure and negative ...
WebSplit Hopkinson Pressure Bar (SHPB) has been widely used as a tool to measure mechanical properties of a material at high strain rates, ranging from 500/s to 1000/s [1]. The stress-strain data at high strain rate is needed in the analysis of structure response loaded at very short time as impact loads, blast loads, etc. Webcompression was calculated as the area under the stress-strain curve. The dynamic behavior of the composite was investigated using the split Hopkinson pressure bar technique. It was found that ceramic-elastomer composites effectively dissipate the energy. Moreover, a ballistic test was carried out using armor piercing bullets. Pokaż mniej
