Abstract
The complexity and irregularity of the internal structure of aluminum foam and the particularity of the fabricating method make it difficult to establish a three-dimensional model that can accurately reflect the internal structure of aluminum foam-polyurethane composites. This study presents a method of three-dimensional reconstruction of the Materialise’s Interactive Medical Image Control System (MIMICS) adjacent mask based on Digital Imaging and Communications in Medicine (DICOM) data. Firstly, spherical open cell aluminum foam-polyurethane composites with different pore sizes (5 mm, 7 mm, 9 mm) were prepared. Then the corresponding DICOM data of the spherical open cell aluminum foam-polyurethane composites were obtained by CT-scan. Based on adjacent mask, the three-dimensional simulation model of spherical open cell aluminum foam-polyurethane composites was successfully reconstructed in MIMICS. In order to verify the feasibility of this modeling method, a quasi-static compression simulation of the three-dimensional simulation model was carried out by ABAQUS, and the simulated stress-strain curves were acquired. The quasi-static compression experiments were performed on the prepared aluminum foam-polyurethane composites, and the experimental nominal stress-strain curves were obtained. The simulated nominal stress-strain curves were compared with the experimental nominal stress-strain curves. Results show that the two curves are basically the same. The feasibility and accuracy of the three-dimensional modeling method for the aluminum foam-polyurethane composites are verified.
