A parametric study on compressive characteristics of Wire-woven bulk Kagome truss cores

Compressive behaviors of the Wire-woven bulk Kagome (WBK) cores fabricated of stainless wires are experimentally investigated. Effects of geometrical parameters such as the wire diameter, strut length and number of layers on the compressive behaviors are studied. Also, behaviors of two different types of the specimen configurations, namely, pointed faced and flat faced specimens are compared to each other and analyzed. As the number of layers increases, the strength of the specimens slowly decreases. The compressive strength of WBK dominantly depends on the slenderness ratio. Difference in the specimen configurations results in the significant difference of the stress-strain responses for the specimens with slenderness ratio higher than a certain value. The compressive strength and energy absorption capability of WBK are as good as those of the regular truss type cellular metals, when the relative density is sufficiently high. (C) 2009 Elsevier Ltd.
