Abstract

A quasi-static compression response of regularly cell-structured materials is studied by experimental and analytical procedures. A hexagonal close-packed cell-structure is fabricated by mechanical joining under compressive stress. The nominal stress-strain curve is typical to the cellular solids. It has three stages in deformation: linear elastic, plastic collapsing and densification regions. SEM-Servopulser is also used to describe the sequence of deformation images during uniaxial compressive test. Elasto-plastic model can predict quantitatively the compression behavior of copper cell-structured materials. Besides the relative density, the loading condition plays an important role on the deformation mode change and loading capacity. With increasing the contact radius ratio to cell wall thickness, the symmetric deformation changes itself to asymmetric deformation.
