INFLUENCE OF THE NOSE SHAPE OF PROJECTILES ON THE PENETRATION CHARACTERISTICS OF ALUMINUM HONEYCOMB SANDWICH PLATES by HU Jing, LU MingJian, ZHANG Yong, ZHANG YinBo

“…The aluminum honeycomb sandwich plates were impacted by the hemispherical-nosed projectiles and the bluntnosed projectiles launched by a one-stage gas gun,and the influence of the nose shape of projectiles on the ballistic limits,the failure mechanisms of the targets and energy absorption efficiency was analyzed.The results show that the ballistic limit of bluntnosed projectile is higher than hemispherical-nosed projectile,and the nose shape of projectile has a significant effect on the failure mode of aluminum honeycomb sandwich plates.The energy absorption efficiency of sandwich target against blunt-nosed projectile impact is significantly higher than hemispherical-nosed projectile,but the difference between the energy absorption efficiency decreases with the increase of the initial kinetic energy.…”

Characterization of Acoustic Emission Parameters during Fracture Process of Siltstone with Prefabricated Void by Xiaorong Liu, Lulin Zheng, Hengyi He, Qing Qiu, Ziqi Liu, Xuefeng Li, Lin Yan, Gang Huang

“…The research results show that there are multiple stress drops before the deformation and failure of the rock sample with prefabricated drill holes; there is a positive correlation between the diameter of the drill hole and the power law index of the stress drop distribution; the acoustic emission activity of the rock during the deformation and failure process can be indirectly reflected the evolution of microfractures; the energy probability density function under different borehole diameters conforms to the power law distribution; the critical exponent obtained by the maximum likelihood estimation has an optimal plateau value, which can accurately characterize the power exponent of the energy distribution; the launch waiting time and aftershock sequence have a good power-law distribution in logarithmic coordinates. …”
