AB This article presents a numerical study on the mechanical behaviour of damaged micro-lattice (ML) blocks submitted to uniaxial compressible loads. The numerical model is implemented in the commercial finite-element code Abaqus/Standard. From the finite-element model, the initial stiffness and the Yield stress of ML blocks are calculated. The damage in ML blocks is modelled as manufacturing defects, that are included in the ML structures using a random algorithm implemented in MatLab. The numerical model is validated with experimental data from uniaxial compression tests carried out on ML intact blocks by other authors. The analysis of the mechanical behaviour of ML blocks is presented in terms of variations of damage percentage, cell type and cell size.
