Chiral Crushing: A Numerical Analysis of Auxetic Chiral Lattice Structures In Compression

This study aims to conduct a numerical analysis of auxetic chiral lattice structures under compression, with a focus on fatigue loading. Assigning polylactic acid (PLA) as the material, finite element models of both individual unit cells and lattice structures will be developed and subjected to simulated loading. The simulations will encompass a range of loading conditions, including both linear and non-linear analyses, to observe the deformation behavior of the structures and measure the effects of fatigue on the magnitude of the negative Poisson ratio.
