Optimization on compressive strength of sandwich plates with internal arborescent microstructure

Abstract

The subject of this work is the optimization of a topology for sandwich plates with an internal arborescent microstructure. Here, we propose a parametric approach to the optimization using visual programming methods in the Dynamo Sandbox environment. An internal structure of the sandwich plate was optimized in terms of minimizing the weight of the entire structure in relation to the compressive strength. Several variable parameters in the optimization process were applied: lengths of individual tree levels, their cross-sections and locations of nodes. To validate obtained results of the optimization process, a 3D model of the plate was printed and tested on compressive strength. The results were also analysed and compared with other authors’ research.
