Analysis of mechanical properties of lattice structures with stochastic geometric defects in additive manufacturing

The lattice structure manufactured by additive manufacturing has geometric defects, which makes geometric shapes different from initial design. This research aims to incorporate stochastic geometric defects into the strut elements of a lattice structure to enhance predictive capabilities of simulation and analyze the influence of difference defects on mechanical properties. Here, X-ray computed tomography (CT) was used to extract the shape and...
