Summary

The Advanced Structural Design and Evaluation Group in Synergy Ceramics Laboratory has been developing a method which analyzes stress distribution and deformation in porous ceramics under mechanical stresses. An image-based technique for modeling porous alumina has been developed using 3-dimensional high resolution X-ray CT. From the 3-D CT image, a local microscopic model of the porous specimen is extracted using voxel mesh method. The homogenized elasticity of the microscopic model is used as input data in the voxel mesh calculation, and the global stress distribution in a macroscopic model of a 4-point bending test specimen was obtained. Using the data the local stress distribution of the microscopic model was also obtained.
