Compressive Strength of Wire-woven Bulk Kagome with Various Orientations

To date, the mechanical behavior of WBK under compression has been studied for a certain orientation in which WBK is presumed to have the highest strength. In this study, the compressive strength of WBK various orientation are presented. First, analytic solutions are derived with consideration of wire waviness and brazed joints at the cross points among wires. Numerical simulations are performed with a unit cell model with periodic boundary conditions. Compressive strengths depending on the orientation estimated by the approaches are compared with experimental results on failure maps to prove the validity. Practical and physical meanings of the results are discussed.
