20.500.12556/DKUM-92239 Mechanism elucidation of high-pressure generation in cellular metal at high-velocity impact Cellular metals exhibit diverse properties, depending on their geometries and base materials. This study investigated the mechanism of high-pressure generation during the high-velocity impact of unidirectional cellular (UniPore) materials. Cubic UniPore copper samples were mounted on a projectile and subjected to impact loading using a powder gun to induce direct impact of samples. The specimens exhibited a unique phenomenon of high-pressure generation near the pores during compression. We elucidate the mechanism of the high-pressure phenomenon and discuss the pore geometries that contribute to the generation of high pressures. cellular metal high-pressure high-velocity impact computational simulation metal jet kovinski materiali celični materiali visoki pritiski hitrost udarna žilavost preiskava materiala računalniške simulacije kovinski curek true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/metals © 2022 by the authors.
