Abstract

Lattice structures fabricated via Additive Manufacturing (AM) offer improved performance over traditional manufacturing methods, however, predicting their mechanical behaviour both accurately and with acceptable computational efficiency remains a challenge. AM associated defects combined with multiple high aspect-ratio strut elements require fine 3D finite-element (FE) meshes; resulting in high computational complexity that limits the number of lattice unit cells that can be practically simulated. Alternatively, Euler-Bernoulli or Timoshenko beam elements can be specified to reduce computational complexity. However, these beam elements are typically based on idealised representations that ex..
