Abstract

Dia-Core is a newly devised core panel formed by gluing/welding two same shaped panel pieces which have periodical indents. It has good cost performance due to easy press forming. Therefore, it is expected to become a new core which can compete with honeycombs from the total points of view. The basic model of Dia-Core is based on Octet-Truss developed by Fuller, and it consists of tetrahedra and octahedra. Various shaped modified models are devised systematically by varying the geometrical patterns that appear on the panel surfaces. These pattern variations can be ruled by two geometric parameters, truncation [k] and separation [s]. In this paper, the single stage forming simulations of Dia-Core panel are performed to investigate the relation between formability of press working and these parameters by using explicit FEM technique. As a result, the models having the good formability are clarified.
