【摘要】 采用静态力学法 ,分析了中等密度、低孔隙率的泡沫钼静压全程加载 -卸载特性曲线。研究了在不同初始密度下该材料的静压吸能特性。计算表明 ,泡沫钼在静压过程中具有较高的吸能量 ,吸能效率较高。但预压后的泡沫钼吸能量和吸能效率均有所下降。更多还原

【Abstract】 The characteristic curve of full loading unloading with mid density sintered porous Mo specimens has been analysed under lower hydrostatic pressure. Under the circumstance, the energy absorbing property of the foamed material was studied in various diameters. The porous Mo show higher energy absorbing quantity and efficiency by relative calculation .However, these evidences are appreciably minished after pre pressuring the specimens.更多还原
