Mechanical Properties of Semi-Regular Lattices

• The in-plane mechanical properties of 7 semi-regular lattices were derived analytically. We found a stretching-dominated topology with an elastic buckling strength 43% higher than regular triangular lattice. One bending-dominated tessellation is 85% stiffer and 11% stronger hexagonal seven analytically for uniaxial compression shear. These analytical expressions then validated using Finite Element simulations. Our analysis showed that one stretching-dominated; two are in but shear; four bending-dominated. To assess their potential, the these topologies compared to lattices. be In addition, three had modulus fact, was This would ideal applications requiring high stiffness energy absorption.
