On Stiffness, Strength, Anisotropy, and Buckling of 30 Strut?Based Lattices with Cubic Crystal Structures

Architected cellular structures are increasingly receiving attention in numerous applications due to advances additive manufacturing and their promising multi-functional properties. Herein, 30 architected strut-based lattices of cubic crystal symmetry developed stiffness strength investigated computationally experimentally. Finite element simulations conducted compute the effective stiffness, yield strength, buckling under uniaxial, shear, hydrostatic loadings. Also, elastic anisotropy is assessed bifurcation analysis performed estimate threshold relative density for each lattice. Selected various densities 3D printed from a polymeric material using selective laser sintering (SLS). The numerical results show that modes deformation whether stretching-dominated, bending-dominated, or mixed differ loading conditions. It observed by combining different lattice hybrid approach, decrease anisotropic behavior obtained, an overall enhancement mechanical properties achieved. rather good agreement with experimental findings. current study can be crucial enhancing structural systems.
