A novel modeling approach of aluminum foam based on MATLAB image processing

A novel modeling approach is proposed to establish the reconstruction geometrical model of aluminum foam based on MATLAB image processing and X-ray computed tomography (μCT) scanning. A two-step mesh method is employed to mesh the reconstruction geometrical model in MATLAB by appropriate selection of node, and then establish the FEM of aluminum foam directly. As shown in figure, only local holes collapse when the amount of compression is 10 mm, and the collapsed positions in three examples are different. It illustrate that calculation is independent on geometric modeling algorithm.
