Uncertainty quantification of microstructure variability and mechanical behaviour of additively manufactured lattice structures

Nina Korshunova, Iason Papaioannou, Stefan Kollmannsberger +2

Process-induced defects are the leading cause of discrepancies between as-designed and as-manufactured additive manufacturing (AM) product behavior. Especially for metal lattices,…

Finite Cell Method for functionally graded materials based on V-models and homogenized microstructures

Benjamin Wassermann, Nina Korshunova, Stefan Kollmannsberger +2

This paper proposes an extension of the finite cell method (FCM) to V-rep models, a novel geometric framework for volumetric representations. This combination of an embedded domain…
