The Inverse Honeycomb Structures in Numerical Modeling and Experiment

Małgorzata JOHN, Antoni JOHN, Wojciech SKARKA

Abstract


Based on previous research, we proposed changes in the classic honeycomb structure. We have changed the approach to modeling. In a classic structure, cells are modeled using the walls that form them. In the modified structure, the main modeled element is the hexagon-shaped void. The distribution of cells was proposed as in a truss. In full places the spaces were smaller and in empty places the cells were larger. We changed the size of cells and the transition between cells in different layers.

In comparison to previous research, it was necessary to enlarge the models. This was due to the limitations of incremental technology, which was used to fabricate samples – FDM. This technology introduced limitations of changes that the structure underwent. We selected several types of models as a result of the numerical simulation and produced. Then, experimental tests were carried out on them – the same as in numerical simulation. In the final stage, we compared the obtained results.
