This study investigates the elastic response of a tessellated structure based on cylindrical struts generated along the wireframe of a truncated octahedron (the Kelvin cell). The structure has two variable dimensions (strut thickness and strut length), the relative density being plotted as a function of the given parameters and ranged between 6.7 10~(-4) and 0.217. The variation of the relative stiffness of the structure was determined as a function of relative density. The size effect was also investigated by determining the elastic response for different cell numbers.
