Fig.3 Stress-strain curves of the Ti-6Al-4V reticula-ted meshes with different rhombic dodecahedron unit cells (a), the unit cell designed by the Materialize software (b), unit cells designed to increase the bending component of the load applied on the struts (c, d)[13] (P is the load applied to a strut (EF). P1 and P2 are two components of P along the bending and buckling deformation directions)
