Design and modelling of bioinspired 3D printed structures

Abstract

[EN] Metamaterials are those that, through human engineering, have unusual properties that cannot be commonly found in nature. Recently, these metamaterials have been gaining importance due to the introduction of additive manufacturing technologies. Specifically, metamaterials known as lattice structures have advantages over bulk solid materials, such as increased strength and specific stiffness. However, in order to exploit these advantages of these exotic materials, we need robust and accurate tools to tailor and design their properties. The objective of this work is to present a complete systematic study of the different approaches for metamaterial computational design evaluating their advantages and drawbacks in terms of computational efficiency and accuracy in predicting the metamaterial mechanical properties.
