| Abstract: | Based on synchrotron radiation computed tomography,three-dimensional internal structures were reconstructed for aluminum foam specimens.And the three-dimensional model of aluminum foam specimens was used to study the deformation process,Mises stress and the distribution of elastic-plastic region by finite element method.The research results show that it is a very effective method using the three-dimensional model based on the synchrotron radiation computed tomography to analyze the mechanical properties of materials. |
