Mechanical modeling of polymer foams

The research program aims to develop advanced polymer foams with spatially controlled density distributions, designed using topological optimization techniques. The goal is to create lightweight cellular materials with better mechanical performance compared to conventional uniform-density foams, using the same amount of material. The research combines numerical modeling, designing optimal density distributions, and developing controlled physical foaming processes. Special attention will be given to designing preforms and controlling gas transport in the polymer to achieve the desired morphologies. The produced materials will be characterized using microscopy and three-dimensional morphological analysis techniques. Mechanical performance will be tested through bending tests under quasi-static and dynamic conditions, including impact tests.
