Metal Foam Analysis Based on CT Layers

Abstract

The geometrical modelling of metal foams remains one of the greatest challenges facing researchers in the field. In this paper the analysis of the inner structure of closed-cell aluminium foam - an essential part of the construction of an idealized foam model - is presented. With the application of special purpose software the properties of the foam cells can be mapped precisely and the results applied to the development of idealized foam geometry constructed in CAD applications.

Linear elastic finite element investigation of titanium specimen produced by Additive Manufacturing

“…The University of Debrecen has an EOS M290 type 3D printer in the Biomechanical Laboratory of the Orthopaedic Clinics, which uses titanium alloy powder as a raw material. [2][3][4][5][6] 2.2 CAD modelling of specimens 4 types of specimens were modelled with CAD software according to the ISO 13314 standard. It takes many steps to arrive to the simulation of full geometries, therefore standard compression test specimens were tested first.…”

The Influence of Foaming Agents on Aluminium Foam Cell Morphology

“…Afterwards, they are used to mathematically reconstruct a 3D volume that represents the real foam specimen. On the obtained 3D models, any cross-section of the sample can be analysed [43][44][45]. Subsequently, those samples can be subjected to mechanical testing or exploitation since they were not destroyed during testing.…”
