• Experimental test
• FEM
• Lattice
• Part design

Additive Manufacturing is employed in many different fields, and one of the most fascinating features that can be created and designed are the “lattice structures”. These mesoscale lattice structures can be considered as a custom designed cellular solid, and analysed by following the theory proposed by Gibson and Ashby. Moreover, the many limits in the process cause the need for an experimental testing and analysis of these structures, and a subsequent numerical correlation in order to obtain a valid instrument for the design of a generic part. In this study are firstly proposed the results of the experimental campaign involving different lattice trabecular structures, both for tensile and compressive tests.
These results are used to numerically correlate the cellular solid, in order to simulate a thin walled crash absorber for a vehicle, investigating also the interaction between the skin and the lattice and how it affects the crashworthiness of the absorber.
In the end, some of the most interesting TPMS like the double gyroid are exposed and created, and are also used as a filler of a suspension arm that is numerically analysed.
