Bending behavior of additively manufactured lattice structures: numerical characterization and experimental validation
Nina Korshunova, Gianluca Alaimo, Seyyed Bahram Hosseini +6
Selective Laser Melting (SLM) technology has undergone significant development in the past years providing unique flexibility for the fabrication of complex metamaterials such as o…
Image-based numerical characterization and experimental validation of tensile behavior of octet-truss lattice structures
Nina Korshunova, Gianluca Alaimo, Seyyed Bahram Hosseini +6
The production of lightweight metal lattice structures has received much attention due to the recent developments in additive manufacturing (AM). The design flexibility comes, howe…
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…
A 3D benchmark problem for crack propagation in brittle fracture
Lisa Hug, Stefan Kollmannsberger, Zohar Yosibash +1
We propose a full 3D benchmark problem for brittle fracture based on experiments as well as a validation in the context of phase-field models. The example consists of a series of f…
Integrating CAD and Numerical Analysis: 'Dirty Geometry' handling using the Finite Cell Method
Benjamin Wassermann, Stefan Kollmannsberger, Shuohui Yin +2
This paper proposes a computational methodology for the integration of Computer Aided Design (CAD) and the Finite Cell Method (FCM) for models with "dirty geometries". FCM, being a…
From geometric design to numerical analysis: A direct approach using the Finite Cell Method on Constructive Solid Geometry
Benjamin Wassermann, Stefan Kollmannsberger, Tino Bog +1
During the last ten years, increasing efforts were made to improve and simplify the process from Computer Aided Design (CAD) modeling to a numerical simulation. It has been shown t…
