摘要
因基体在阻尼和塑性方面的差异,使多孔镁在阻尼性能和压缩应力应变行为上显示出与多孔铝有很大的差别。多孔镁具有更高的阻尼本领、更平坦的压缩应力-应变平台,在冲击能吸收结构中应用应更具有优势。
A comparative study was carried out on the damping property and compressive stress-strain behavior between porous Mg and porous Al.The results indicate that there exists a large difference between them due to the variance in damping and plastic property of their basal body.The porous Mg exhibits a higher damping capacity,a longer and lower stress plateau than porous Al,suggesting more superior energy absorption and damping properties.
