Recently, to meet the requirement of machine industry, there has been an increased focus on the development of porous metal as a high-strength material despite its low density. To evaluate its properties and quality, material testing is usually conducted. However, it is more efficient to perform computer simulation evaluations using finite element analysis. In fact, converting a large piece of porous metal into digitized mesh data is significantly difficult because of its complex inner structure. The X-ray computed tomography scanning technique enables us to obtain the information regarding the internal structure of the metal. Furthermore, a reconstruction algorithm produces volume data of the test object. In general, conventional methods are utilized to generate mesh data from volume data, but a key drawback is that they generate too many elements, resulting in high computational cost. We propose an approach to generate meshes for porous structures by modeling each pore using spheres from volume data. Data conversion is conducted through a series of processes namely labeling, spherical approximation, shape approximation, region segmentation, and meshing. The result verifies the feasibility of the proposed method, which generates shape-approximated and finite-element-simulation-available mesh data using fewer elements.
