| Research Abstract |
We proposed investigation of geometrical and mechanical properties of Foraminifera and Radiolarian skeletons in order to clarify what is an optimal structure under micro gravity condition. Results are summarized in the following three points: 1) Using micro X-ray computer tomography, we can obtain three dimensional information with sufficient resolution of both fossils and recent Foraminifera and Radiolarian skeleton. 2) We propose mathematical models of chamber arrangement of Foraminifera, and evaluate the proposed model in contrast with three dimensional information obtained by micro X-ray CT. 3) The observation of enlarged plaster models based on three dimensional information provides some geometrical characteristics of Radiolarian skeletons. Also we carried out FEM analysis using voxel finite element models.
